متن کاملStable and accurate wave-propagation in discontinuous media
A time stable discretization is derived for the second-order wave equation with discontinuous coefficients. The discontinuity corresponds to inhomogeneity in the underlying medium and is treated by splitting the domain. Each (homogeneous) sub domain is discretized using narrow-diagonal summation by parts operators and, then, patched to its neighbors by using a penalty method, leading to fully e...
متن کاملHigh-order accurate modeling of electromagnetic wave propagation across media - Grid conforming bodies
The Maxwell equations contain a dielectric permittivity e that describes the particular media. For homogeneous materials at low temperatures this coefficient is constant within a material. However, it jumps at the interface between different media. This discontinuity can significantly reduce the order of accuracy of the numerical scheme. We solve the Maxwell equations, with an interface between...
متن کاملElectromagnetic Wave Propagation in Media Consisting of Dispersive Metamaterials
We establish the well-posedness, the finite speed propagation, and a regularity result for Maxwell’s equations in media consisting of dispersive (frequency dependent) metamaterials. Two typical examples for such metamaterials are materials obeying Drude’s and Lorentz’ models. The causality and the passivity are the two main assumptions and play a crucial role in the analysis. It is worth noting...
متن کاملNonreciprocal Electromagnetic Wave Propagation in Ionized Gaseous Media
The nonreciprocal propagation of electromagnetic waves in ionized gaseous media is discussed, and experimental observations are reported in this paper. The classical Faraday experiment in the optics of anisotropic media has suggested an analogous phenomenon at microwave frequencies. The anisotropic behavior of the free electron gas which is immersed in a magnetic field and subjected to an incid...
