This paper presents a hybridized discontinuous Galerkin time-domain (DGTD) method with boundary integral equation (BIE) method to accurately solve the electromagnetic scattering problems. The weighted Laguerre polynomials are chosen as temporal entire basis functions to expand the temporal variables, which makes the proposed scheme free from Courant-Friedrichs-Lewy (CFL) condition and promising for...
In this paper, we discovered an advanced GLLH Invisible Electromagnetic Cloak with relative EM parameter not less than one for any thickness spherical annular cloak, i.e., relative electric permittivity εr ≥ 1, εθ ≥ 1, εϕ ≥ 1 and magnetic permeability μr ≥ 1, μθ ≥ 1, μϕ ≥ 1 in the GLLH cloak sphere annular layer, for any 0 < R1 ≤ r ≤ R2. We completely and theoretically proved that our GLLH cloak...
The hybrid finite elements-boundary integral (FE-BI) method has been one of the most widely used numerical methods for the full wave solution of time-harmonic electromagnetic (EM) problems. The method first divides the computational domain into interior and exterior regions. The EM fields in the interior region are discretized using the finite-element method (FEM) and the fields in the unbounded exterior...
