Abstract
Abstract—In this paper we present the theoretical analysis of
the effects of standing waves between coupled horn antennas that
can occur in terahertz quasi-optical systems. In particular we illustrate
the approach for the case of two coupled horn antennas as
the distance between them is varied. The full mode matching scattering
matrix approach is based on combining a standard waveguide
mode description of the horn antenna and a quasi-optical
Gaussian beam description of the free space propagation. Track is
kept of both the backward and forward going components of the
propagating fields.We compare theoretical predictions with actual
experimental test results for a quasi-optical system operating at a
frequency of 0.480 THz
