Abstract

Abstract: Mode condition of elastic wave in solid-fluid rectangular doping phononic crystals is obtained with restriction conditions of elastic wave.Response of defect mode to mode quantum number and length of rectangle are calculated.Multichannel filters are realizated with relationship of defect mode and mode quantum number.Harmonious filters are obtained as defect mode varies with mode length of rectangle.

Key words: rectangular phononic crystal, elastic wave, restrictions, filter
