In this paper we implement full model using Comsol Multiphysics software, leading to study both SAW structures, resonator and delay line. A general finite element method (FEM) of two-dimensional piezo-magnetic devices is used.

This work deals with the determination of the effective response of a multilayered or laminated heterostructure composed of materials with an arbitrary coupled anisotropic behavior. In particular, we elaborate a fully algebraic technique for obtaining the homogenized parameters of a magneto-electro-elastic system (artificial multiferroic).

Coplanar transmission lines (CPW) are realized on polydimethylsiloxane (PDMS) substrate in order to characterize its complex permittivity, from 1 to 220 GHz. By varying the complex permittivity, the propagation constant of the PDMS-CPW calculated with full wave software is matched to those extracted by de-embedding techniques using S-parameters measurements. The real permittivity evolves from 2.9...
