F. Zhang et Jm. Fu, EFFICIENT ANALYSIS OF A DIELECTRIC POST IN A RECTANGULAR WAVE-GUIDE BASED ON THE 2-DIMENSIONAL FD-TD METHOD, Microwave and optical technology letters, 6(7), 1993, pp. 407-410
A modified two-dimensional FD-TD method is used for the analysis of an
H-plane waveguide loaded with a dielectric post of arbitrary shape, s
ize, number, and location, and the dielectric post resonances and the
application of measurement of permittivity constant are discussed. The
numerical results are in good agreement with data available in the li
terature, and the versatility of this approach is given.
