Abstract: We study wave propagation in periodic materials with dissipation using two different formulations. An د‰(k)formulation yields complex frequency solutions for nonvanishing dissipation whereas a k(د‰)formulation leads to ...

Abstract: This paper reports recent results from an ongoing effort to develop an implantable accelerometer-based heart-monitoring device for ischemia monitoring. The latest device prototype utilizes a new and more compact accelerometer ...
