Ray-Tracing Study of Artificial Black Hole in Electromagnetic Field

Tongxing Li, Xiaoyu Tan, Zhimin Zhang, Yongfeng Zhang
The artificial black hole has the name “Black Hole”, although the size of the “Mini”, but any passing electromagnetic wave or light, it is impossible to escape its gravity. Based on the theory of artificial black holes, it is possible to design wave absorbing materials with excellent performance. In this paper analyzes the trajectory equation of light rays in black holes using the Hamilton principle. In the last chapter of the article, the feasibility of the theory in this paper is verified by u...

Problems with the Klein-Gordon Theory

Eliahu Comay
The electromagnetic domain comprises two kinds of physical objects—electromagnetic fields and electrically charged particles. Therefore, the structure of a comprehensive electromagnetic theory is a coherent union of two theories. One theory describes electromagnetic fields, and the second theory describes electrically charged particles. An obvious requirement says that a comprehensive electromagnetic theory must be a coherent union of a theory of electromagnetic fields and a theory of electrical...

The Significance of the Distinction between a Necessary Condition and a Sufficient Condition

Eliahu Comay
The distinction between the concepts of a Necessary Condition and a Sufficient Condition is a fundamental element of mathematics. This issue certainly applies to physics which has a mathematical structure. However, this work shows that sometimes physical textbooks ignore this distinction. An analysis of the conserved 4-current of the Noether theorem proves that this issue is extremely important. The analysis uses the dimension of the Lagrangian density and the corresponding dimensi...

Mode Analysis in a Spherical Resonator

Tongxing Li, Yongfeng Zhang
The problem of spherical resonator for electromagnetic wave propagation is one of the hot topics; in this paper, we give spherical coordinate transformation and solution of Helmholtz equation, through spherical Bessel function and spherical Neumann function to analysis mode in spherical resonators. Finally, the distribution of electromagnetic wave in spherical resonator is given by numerical example.

Elementary Particles’ Electrodynamics

Isaak Man’kin
We suggest a field theory based on a generalization of Maxwell’s equations of electromagnetism, which allows one to describe the various elementary particles’ structures. It seems to us, that such a theory must exist because under suitable reactions, particles can turn into particles of other forms and that the photon which partakes in many reactions, being a quantum of electromagnetic field, is described by the Maxwell equations. The fact that particles are supposed to have an internal structur...
