잘린 환형 산란체에 유도되는 전류 밀도 해석 = An Analysis of Current Density Induced on Cleaved Circular Scatterers

다국어 초록 (Multilingual Abstract)

In the study of antenna theory, a knowledge of the current distribution is of fundamental importance. Such data may be obtained either by measurement or by solving the antenna integral equation. Integral equations are difficult to solve even for the simplest case of a dipole antenna. However powerful computer enable the use of integral equation method in larger range. The use of high speed digital computers not only allows more computational power, but it makes practicable methods of solving repetitive calculation.
In this paper cleaved circular scatterers fed by coaxial cable is described to obtain current density in the various environments. To illustrate the use of presented formulation method of integral equations it is applied to the cleaved circular scatterers. Also, the current density induced by an incident plane wave illumination are obtained for the cleaved circular scatterers. Results obtained are very close to Taylor's results of cylindrical antenna.
