Abstract :
Using PML as a lateral boundary in waveguide analysis introduces artificial modes and other unexpected effects. The paper presents results of a finite-difference frequency-domain approach, verified for a leaky-wave antenna, and provides analytical considerations supporting these findings. Particularly, the problem of detecting the desired modes out of the mode spectrum is addressed.
