Abstract

Different quasi-optical schemes are considered in this report, and their ability to work well is evaluated and discussed. All these schemes are based on an optical transmission, with or without focusing mirrors, between radiating antennae (RA) and the grill, which couples the beam to the plasma. Two basic types of LHW launchers are taken into account: (i) the radiating antennae and the grill are composed of rectangular waveguides carrying the fundamental TE(10) mode; (ii) the radiating antennae launch Gaussian beams and the grill is made of optical rod arrays. The present work aims at determining some devices of interest for which further calculations and improved conceptual design would be justified. Accordingly, this work has to be considered as a preliminary study, eliminating what look like low-capability devices and, inversely, yielding some schemes and directions of research.
