Diffraction selection in screened quasi-optical resonators
Abstract
Experimental results are presented concerning the influence of cylindrical screens on the spectral characteristics of long-focus and short-focus open resonators. An effective method for the mode selection of screened open resonators is proposed which is based on the use of metal-dielectric cylinders with a periodic structure on their internal surface.
