Global and Local Field EM Modeling for PHC Dispersion and Metamaterial Cloak Design
In this paper, we propose GL Electromagnetic (EM) field modeling for dispersion of the photonic crystals (PHC) and metmaterial cloak design simulations. Their medium is a finite inhomogeneous domain which is embedded into the infinite homogeneous space. The finite inhomogeneous domain is divided to a set of sub domains. The electromagnetic field through the PHC or cloak is presented as explicit recursive sum of the integrals in the sub domains. The analytical EM field and the Greens tensor in the background domain are called initial Global field. The Global field is updated by Local polarization and magnetization scattering field successively sub by sub domain. Once all sub domains are scattered, the GL EM field solutions are obtained. Unlike FEM and FD methods, GL method directly assembles inverse matrix for getting solution and does not need to solve lager matrix equation. The GL method is great faster and more accurate than the FEM and FD method. Moreover, it does not need artificial boundary for truncating infinite space. The two scopes of the GL EM modeling simulation methods are proposed in this paper. One is the GL EM modeling method for dispersion design simulations of the photonic crystals, other is GL EM metamaterial cloak simulation. Both are attractive interesting research object in the new EM materials.
