A study of coupling mechanism between two dipoles integrated within a conductor-backed thin dieelectric layer above earth using asymptotic evaluation

점근적 근사를 사용한 지표면 위에 놓여 있는 한쪽 면이 도체로 된 얇은 유전체 층 내부의 두 다이폴 사이의 상호 결합 원리에 관한 연구

An electric field due to point dipole within conductor-backed thin dielectric layer above the earth is calculated by using saddle point method When the dielectric layer is thin enough to support a cutoff mdoe, we show that the field may be approximated by sum of contributions of branch points of TE mode and poles of tM mode and that the branch points and poles contributions are interpreted as an evanescent lateral waves and leaky waves, respectively.
