Abstract
A solution is presented for TM plane wave scattering from a corrugated structure with zero thickness plates and two different, alternating groove depths. Expressions for the reflection coefficients, obtainable for any number of propagating modes, are explicitly shown in the frequency range corresponding to a single (TEM) mode propagation in the plates and two diffracted spectral orders present in the free‐space region. The scattering matrix for the junction discontinuity is derived with the help of an interesting procedure. The solution has potential applications in the study of Wood anomalies of diffraction gratings and guided waves on modulated structures. The procedure may easily be generalized to an arbitrary number of different groove depths.Keywords
