Electromagnetic Wave Scattering at Double Frequency from Antennas with Nonlinear Load

Electromagnetic Wave Scattering from Rough Penetrable Layers

We consider scattering of time-harmonic electromagnetic waves from an unbounded penetrable dielectric layer mounted on a perfectly conducting infinite plate. This model describes for instance propagation of monochromatic light through dielectric photonic assemblies mounted on a metal plate. We give a variational formulation for the electromagnetic scattering problem in a suitable Sobolev space ...

Low-Frequency Electromagnetic Scattering

The main result of this paper is to reduce the calculation of higher-order terms in the asymptotic expansions of the electric and magnetic elds at low frequencies to the solutions of certain canonical problems. We also provide a new and simple variational proof of the convergence of the electric and magnetic elds solutions of the scattering problem for the Maxwell equations as the frequency goe...

Electromagnetic Wave Scattering from Particles of Arbitrary Shapes

We consider a general solution of the electromagnetic wave scattering problem for arbitrarily shaped homogeneous particles, whose surface can be expressed by a function of angular coordinates, using a Laplace series expansion. This can include regularly shaped particles (e.g., ellipsoids and cubes) as well as irregularly shaped particles like Gaussian spheres. For calculations of scattering pro...

Nonlinear Approximations for Electromagnetic Scattering from Electrical and Magnetic Inhomogeneities

We extend linear and nonlinear approximations for electromagnetic fields to a medium with inhomogeneous distribution of both electrical and magnetic material properties. These approximations are presented in the form of tensor integrals over a domain with anomalous pa­ rameters . The developed approximations combine the linear and nonlinear estimations depending on the ratio of complex conducti...
