In this paper, we present a formulation for a domain decomposition method using boundary integral equations in order to solve wave scattering and antenna radiation on large platforms covered by a thin dielectric coat via an impedance boundary condition.
In this paper, we present a non-overlapping domain decomposition method using integral equations in the frequency domain for the resolution of wave scattering from metallic objects. The objective is to use multi-domain modelling to process multi-scale structures. This method is flexible thanks to an independance between sub-domains and relying on the local… (More)
Ground wave radiation of Low Frequency Antennas is well known for the canonical case of a flat, azimuthally homogeneous, soil. In this paper, more complex kinds of environment are considered in the surroundings of the antenna or in the far field. Both of them are treated by FDTD. Some realistic environments are studied in the near field zone including… (More)
In this article is a problem of electromagnetic compatibility (EMC) presented bringing in several cavities, mutually coupled between holes of small size with respect to the wavelength. The coupling function between cables placed in multiple cavities is estimated by a numerical method based on a topological approach. The intermediate data of the problem… (More)
