Abstract

The scattering process of waves by a planar junction of two half-planes, one of which is impedance and the other a reflectionless metasurface, is studied. The transition boundary method is considered. The scattered geometric optics field is obtained by subtracting the initial fields from the total geometric optics field. The diffracted field is obtained by considering the relation between diffracted and scattered geometric optics field expressions in the transition boundary. The ultimate expressions of the fields are examined numerically for different parameter groups.
