Abstract

In this paper we explore the possibility of using sections of overmoded smooth-wall circular waveguideinstead of an overall corrugated waveguide transmission line to carry strong mm-wave power in ECRHexperiments. To this end we carry out an exact analysis of the transitions from corrugated to smooth-wallwaveguide and optimize the length and size of the smooth-wall waveguide to achieve minimum losses. Thewhole structure is described by a generalized scattering matrix whose elements are obtained using the exactquasi-TE and quasi-TM uncoupled modes in the lossy smooth-wall waveguide.
