Ea. Kraut et al., FDTD SOLUTION OF MAXWELLS EQUATIONS FOR AN EDGE SLOT PENETRATING ADJACENT BROADWALLS OF A FINITE WALL THICKNESS WAVE-GUIDE, IEEE transactions on antennas and propagation, 42(12), 1994, pp. 1646-1648
The finite-difference time-domain (FDTD) method is applied to predict
reflection coefficients for edge slots penetrating the adjacent broads
ides of thick walled rectangular X-band waveguides. Measured and calcu
lated values S-11 are compared to experiment for waveguides terminated
by shorted loads.
