Microwave Review , 2012,
Abstract: On the 12th of May 2011, professor Marin i left the scenes of life but deep and indelible traces of his creative work in science and education are still present, with the significance that continues to grow everyday. Contribution of professor Marin i to the development of telecommunications and electrical engineering in general, as well as the international reputation of our scientists, is tremendous. Considering his contribution to the development of the ETRAN Society (expert sections: Antennas and Propagation – AP, Microwave Technique – MT and Telecommunications) and the establishment of the National Society for Microwave Technique, Technology and Systems, a special section devoted to his rich professional and scientific work was held at the ETRAN 2012 Conference, within the MT expert section. This work represents an introduction of the aforementioned section. Here will be given a summary of the most important results in science and education of academician Marin i , a respected professor, great scientists and a highly remarkable man.

Modeling of microwave applicators with an excitation through the wave guide using TLM method
Ran?elovi? Tijana,Jokovi? Jugoslav,MilovanoviBratislav
Serbian Journal of Electrical Engineering , 2005, DOI: 10.2298/sjee0502137r
Abstract: In this paper, a real microwave applicator with a wave guide used to launch the energy from the source into the cavity is analyzed using 3D TLM method. In order to investigate the influence of the positions and number of feed wave guides to the number of the resonant modes inside the cavity, obtained results are compared with analytical results and results obtained by using TLM software with an impulse excitation as well. TLM method is applied to the both empty and loaded rectangular metallic cavity, and a very good agreement between simulated and experimental results is achieved.

Definition of the border between the far and near field zone for printed antenna arrays with high side lobe suppression
Miliji? Marija,Ne?i? Aleksandar,MilovanoviBratislav
Serbian Journal of Electrical Engineering , 2013, DOI: 10.2298/sjee1301113m
Abstract: The paper defines the border between the far and near field zone of printed antenna arrays. The conventional definition has a limited application in side lobe suppression measurements, especially in the case of high side lobe suppression. The paper particularly details the printed antenna array with 8 radiation elements. Its symmetrical tapered feed network with Chebyshev distribution enables side lobe suppression greater than -44 dB in the E-plane. In addition, the influence of tolerances in the standard photolithographic process has been investigated. The expected tolerances in the standard photolithographic process have been assumed with moderate precision in order to estimate the side lobe suppression degradation due to amplitude and phase deviations, as well as deviations to optimized values in radiating element positioning.

Application of metamaterials for the microwave antenna realizations
Asenov Tatjana,Don?ov Neboj?a,MilovanoviBratislav
Serbian Journal of Electrical Engineering , 2012, DOI: 10.2298/sjee1201001a
Abstract: In this paper, the application of left-handed metamaterials for the realization of microwave antennas has been considered. Special emphasis is placed on lens antennas based on gradient-index metamaterials, and their advantages and enhanced features in comparison with conventional microwave antennas are highlighted.
Some applications of neural networks in microwave modeling
MilovanoviBratislav D.,Markovi? Vera,Marinkovi? Zlatica D.,Stankovi? Zoran 2
Journal of Automatic Control , 2003, DOI: 10.2298/jac0301039m
Abstract: This paper presents some applications of neural networks in the microwave modeling. The applications are related to modeling of either passive or active structures and devices. Modeling is performed using not only simple multilayer perception network (MLP) but also advanced knowledge based neural network (KBNN) structures.
Quality of life and results of total androgen blockade alone and with radiotherapy in the treatment of nonmetastatic prostate cancer

Srpski Arhiv za Celokupno Lekarstvo , 2012, DOI: 10.2298/sarh1208462m
Abstract: Introduction. Hormonal treatment of prostate cancer (CaP) in the form of total androgen blockade (TAB) with or without radiotherapy is applied in metastatic disease and in patients with nonmetastatic and localized disease as well. Objective. The aim of the study was to compare oncological results, residual and newly developed symptoms during treatment and the quality of life in patients with nonmetastatic CaP treated by using Tand in a group treated both with Tand radiotherapy (RT+TAB). Methods. Retrospective analysis of 126 patients with nonmetastatic CaP was performed. Follow-up was 36 months. Seventynine out of 126 patients were treated with Talone and 47 with Tand radiotherapy (TAB+RT). Overall survival, metabolic syndrome appearance and the frequency of nonmalignant complications during treatment were analyzed. Urinary, digestive and sexual symptoms were analyzed, as well as the overall health condition of the patients. Results. Fatal outcome and/or disease progression occurred in 29 out of 126 patients (23%). High risk patients were significantly more frequent in the TAB+RT group (p=0.04). Mortality rate was not different in both groups indicating that better results of treatment were achieved in patients treated with TAB+RT. Metabolic syndrome appeared in 51.6% of Tpatients and in 51.1 of TAB+RT patients, and was significantly more frequent at the end of the follow-up than at the beginning of the treatment (p=0.003 in Tand p=0.01 in TAB+RT group). Urinary symptoms were more frequent than digestive symptoms in both groups. The quality of life was slightly improved after the beginning of therapy to be followed by the tendency of gradual decrease. Conclusion. Both modalities of treatment were efficient. Therapy TAB+RT was more efficient in high risk patients. Metabolic syndrome was more frequent after a long-term administration of therapy than at the beginning. The quality of life was the most affected in sexually active patients.
The crime of aggression between consensus and contestation
Milovanovi? Milo?
Medjunarodni Problemi , 2011, DOI: 10.2298/medjp1101024m
Abstract: The efforts to define the crime of aggression as an international crime are accompanied by many problems. Some countries see it as a sign of salvation against foreign interference in internal affairs, while others see it as a limiting factor in achieving their own interests. In the battle between consensus and contestation every victory was a Pyrrhic one and the price of any compromise was high. However, after the Review Conference of the Rome Statute of the International Criminal Court, which was held in 2010, we have many reasons for optimism. In this paper, the author presents the historical development of the crime of aggression from the theoretical discussion to its criminalization as an international crime. It is through a critical analysis of the norms in international documents and judgments of international courts based on them that we point to all the advantages and disadvantages of defining aggression. In his conclusion, the author predicts the future of the crime of aggression, bearing in mind the latest solutions in theory and practice of international criminal law.
