【Abstract】

<正>Wave problems in periodic structures such as phononic crystals in acoustics have been brought to attention during the past few decades because of their remarkable features.Particularly interesting is a phenomenon called anomaly,in which a slight change of incident waves may cause drastic changes on the scattered
