This study examined the direct effect of individual variables (self-esteem, creative self-efficacy, intrinsic motivation and extrinsic motivation) on the Research and Development (R&D) engineers’ creativity. The data were analysed based on questionnaires returned by 130 R&D engineers attached to fifteen Electrical and Electronic (E&E) firms with R&D department in Penang, Malaysia. The convenience sampling method was employed in getting the samples. The results posited that all individual variables were positively related to R&D engineers’ creativity. The results also reported that there is no significant difference in R&D engineers’ creativity between contract employment type and permanent employment type. The theoretical and practical implications of the study as well as suggestion for future studies were also discussed.
The effect of metal and magnetic slab on
the radiation characteristic of monopole antenna is studied in this paper. The
presence of metal slab changes the antenna radiation pattern and it also
increases the gain up to 4.6 dB. The radiation characteristic of monopole
antenna is determined by the separation distance between planar monopole and
metal slab. In addition, magnetic slab also changes the antenna radiation
pattern and it also increases the gain up to 3 dB. Metal slab makes antenna
generate reflection, but magnetic slab makes antenna generate refraction is
their difference. As to the application slab, the initial pattern of the
antenna without materials was omnidirectional. However, when the materials were
added, its pattern would change, making the antenna to have other usages and
transition effect. They will influence electromagnetic in power systems.
