Abstract
The theory of multielement grid filters is derived and compared with experiment. The properties of the filters can be predicted from a knowledge of the characteristics of the individual grids. The filters are treated as asymmetric Fabry-Perot interferometers coupled and in series. Room temperature and low temperature data for combination filters are presented. The fabrication techniques and materials are described for filters in a dielectric.
