This paper considers creation of an anisotropic cloak that provides mimicry of an elliptic cylinder, covered by it, so that for an external observer this elliptical cylinder looks like circular. The technique of designing such mimicry cloaks using the transformation optics approach is presented. We provided a numerical simulation of such a cloak and evaluated its performance.
At present work use nonsingular invisibility cloak as carpet is offered. Possibility completely the numerical approach to calculation nonsingular invisibility cloak of arbitrary shape is shown. Numerical simulation of invisibility carpet with arbitrary shapes is lead.
The electrodynamical computing model of waveguide junctions with anisotropic filling is designed. This model is focused on the evaluation of electrical properties of monocrystalline dielectrics in the microwave band. The technique of measurement of the components of the permittivity tensor of uniaxial anisotropic crystals is offered.
In the present paper a nonsingular cloak is used as a carpet of invisibility We have shown the possibility to calculate the nonsingular invisibility cloak of arbitrary shape by choosing the elliptical system of coordinates in coordinate transformation. Numerical simulation of invisibility carpets with of arbitrary shapes is performed.
Non-singular coordinate transformation is investigated and expressions for a component of permittivity and permeability are received. Numerical modelling of the corresponding device of invisibility is lead. It is shown that the total size of scattering from the invisibility device in a for zone corresponds to size of scattering from the perfect electric conductor cylinder which is “base” of coordinate...
In this paper we investigated boundary conditions for the impedance circular cylinder covered by a low contrast dielectric thin layer. Expression for the resulted impedance of the cylinder is received. Conditions and boundaries to applicability of the used approach are defined. Effect to an impedance of a covering on the resulted impedance to the cylinder is investigated.
For the problem solution of electromagnetic compatibility and information channels packaging of satellite and TV communications in microwave bands the original narrow-band filters based on high waveguide-dielectric resonators with anisotropic materials have been created. The filters are a section of a cut-off waveguide with flanges which contains one or several dielectric inserts completely filling...
