A new absorbing boundary condition (ABC) is presented for the solution of Maxwell equations in unbounded spaces. Called the Huygens ABC, this condition is a generalization of two previously published ABCs, namely the multiple absorb- ing surfaces (MAS) and the re-radiating boundary condition (rRBC). The properties
Boundary Conditions in Case of Electromagnetic Wave Absorption. BY. T. A. KUDYKINA. Boundary conditions for electromagnetic waves in absorbing media are obtained. The fact is taken into account, that in absorbing media the electric induction has two components: one in phase with the electric field of the incident wave
ABSORBING BOUNDARY CONDITIONS. FOR THE VECTOR WAVE EQUATION. Equation (2) is one example of an absorbing boundary condition. However, if applied to the expansion of Eq. (3) at some finite value of r, the residual is. Andrew F. Peterson. Electromagnetic Communication Laboratory. University of Illinois.
Abstract. In this paper, the theoretical perfectly absorbing boundary con- dition on the boundary of a half–space domain is developed for the Maxwell system by considering the system as a whole instead of considering each com- ponent of the electromagnetic fields individually. This boundary condition allows any wave
and limitations. A special attention is paid to the absorption of the evanescent waves which is a critical question in the matter of ABCs. Index Terms— Absorbing Boundary Condition, ABC,.

Abstract—When time-domain electromagnetic-?eld equations are solved nsing finite-difference techniques in unbounded space, there nust be a method limiting the domain in which the field is computed. This is achieved by truncating the mesh and using absorbing boundary conditions at its arti?cial boundaries to simulate
Numerical examples with the finite-difference time- domain method are presented which demonstrate the high accuracy and confirm the expected rate of convergence of the numerical method.

In this paper we briefly review the derivation of two- and three- dimensional absorbing boundary conditions (ABC's) for mesh truncation in PDE solution of electromagnetic scattering problems, compare the approximate 2-D ABC with its exact counterpart and suggest ways by which the ABCs can be improved. We also.
23 May 2013 We present an absorbing boundary condition for electromagnetic frequency domain simulations of photonic crystals and metamaterials. This boundary condition can simultaneously absorb mul- tiple Bloch-Floquet eigenmodes of a periodic crystal, including both propagating and evanescent modes.
