Jw. Lee et al., TM-WAVE RADIATION FROM FLANGED PARALLEL-PLATE INTO DIELECTRIC SLAB, IEE proceedings. Microwaves, antennas and propagation, 143(3), 1996, pp. 207-210
Flanged parallel-plate radiation of a TM-wave into a dielectric slab i
s investigated. The Fourier transform is used to represent the radiati
on field in the spectral domain and the boundary conditions are enforc
ed to obtain the reflection coefficient in rapidly converging series f
orm, Numerical computations are performed to illustrate the radiation
behaviour in terms of aperture size, frequency, and slab geometry, It
is found that a single-mode approximate solution predicts well the rad
iation behaviour when a flanged rectangular waveguide is excited in th
e TE(10) mode.
