The polarization states of electromagnetic (EM) waves can be effectively manipulated through reflections by a Faraday chiral medium (FCM) reflector, and an arbitrary polarization conversion is feasible via adjusting constitutive parameters of the FCM. Reflection formulas of the FCM reflector are rigorously derived, and the deep mathematical analysis is conducted to propose approaches of manipulating...
In this paper, we have investigated the near field and far field properties of the cylindrical cloak. The total fields are analyzed in detail with the constitutive parameters as tensors, which are defined through Pendry's model. Through the numerical examples we can see that "invisibility" can be basically realized. The result is valid, and it can be concluded that such cloaking can be realized...
The electromagnetic characteristics of the model with an electric line source radiating parallel to a lossless inhomogeneous and anisotropic metamaterial covered infinitely long conductor circular cylinder is investigated in this paper. First, the permittivity and permeability tensors of the metamaterial are defined according to Pendry's model, then the wave equation in the cloak is derived, and through...
By use of the spectral-domain approach, the Weyl's identity and the technique of exponential-integral function, a simple and accurate closed-form expression is derived for dyadic Green's function of planar artificially soft and hard surface. The Green's function is expressed as the sum of three parts: primary field, image field reflected by a perfect electric conductor boundary and field created by...
Two new representations of higher-order transition boundary conditions are presented for uniaxial homogeneous-bianisotropic layers, which are expressed in the vectorial and scalar form, respectively. The differential operators on the tangential field vectors and normal field components are cast into the first- and second-order polynomials in normal derivatives, respectively
By using the residue theorem and exact image method, an efficient expression is derived for the electromagnetic fields of the lightning return stroke current. Sommerfeld-type integrals contained in the field are expressed as the exponential decay surface wave (the pole contributions of the integrand) and the rapidly convergent integrals which can be interpreted as a distributed image source in the...
