M. Aubrion et al., ANALYSIS OF DISCONTINUOUS-LAYER PROPAGATION STRUCTURES BY TRANSVERSE RESONANCE METHOD, Electronics Letters, 29(24), 1993, pp. 2086-2087
The transverse resonance method is used for the accurate analysis of p
ropagation structures with discontinuous substrate layers. The origina
l aspect of the approach is the use of LSE-LSM modes as basis function
s combined with appropriate trial functions which leads to small-size
matrices and reduces the numerical effort. As an example the propagati
on characteristics of a microslab waveguide with finite metallisation
thickness are calculated.
