Abstract

A system of two radiationally coupled corrugated waveguides is proposed for remote coupling. Coupling is achieved owing to diffraction of the waveguide mode on the corrugated waveguide surface. Using Rayleigh-Fourier-Kiselev method, we calculated the dispersion curves of the system and the coupling length on their basis. Coupling length changes periodically when waveguide separation increases, this fact makes the remote coupling possible. Optimum distances between the waveguides are also determined. It is shown that the coupling length is related to the radiation loss coefficient of the single waveguide.
