Complex-Eigenfrequency Band Structure of Viscoelastic Phononic Crystals
The consideration of material losses in phononic crystals leads naturally to the introduction of complex valued eigenwavevectors or eigenfrequencies representing the attenuation of elastic waves in space or in time, respectively. Here, we propose a new technique to obtain phononic band structures wi...
