Based on the extended Stroh formalism combined with the technique of conformal mapping and the Laurent series expansion, Green's functions for an infinite two-dimensional anisotropic magnetoelectroelastic medium containing an elliptical cavity are obtained. The exact electromagnetic boundary conditions on the cavity surface are adopted in this analysis. When the elliptic cavity degenerates into a slit crack, the explicit, closed-form expressions for the coupled fields and the intensity factors are also provided. When the piezomagnetic and electromagnetic constants vanish, our results reduce to existing solutions of the piezoelectric solids with an elliptical cavity, which shows that our results are correct and universal.

Virtually all electromagnetic waveguiding structures support a multiplicity of modes. Nevertheless, to date, an experimental method for unique decomposition of the fields in terms of the component eigenmodes has not been realized. The fundamental problem is that all current attempts of modal decomposition do not yield phase information. Here we introduce a noninterferometric approach to achieve modal decomposition of the fields at the output of a general waveguiding structure. The technique utilizes a mapping of the two-dimensional field distribution onto the one-dimensional space of waveguide eigenmodes, together with a phase-retrieval algorithm to extract the amplitudes and phases of all the guided vectorial modes. Experimental validation is provided by using this approach to examine the interactions of 16 modes in a hollow-core photonic-band gap fiber.

In this work the fundamental problem of the biomagnetic fluid flow in a channel under the influence of an applied magnetic field is studied. It is assumed that the magnetization M of the fluid is varying linearly with temperature T and magnetic field intensity H. For the numerical solution of the problem, which is described by a coupled and non-linear
