Abstract
A nontraditional method of synthesis of metal grating angular and frequency bandpass filters based on the analysis of spectrum of complex eigen frequencies of resonators forming a filter is described. Two types of filters, the resonators of which are formed by two infinite metallic strip periodic gratings in H- or E-plane, are considered. It was shown that filters of the first type has spurious passbands, they are more difficult in manufacturing and suggestion method has an advantage over traditional approach in high frequency range.
