Multiscale model with relaxed boundary conditions for metamaterial calculations

Abstract

The software presented is designed to perform metamaterial calculations via a multiscale model, where an original problem (a metamaterial structure) with a large number of degrees of freedom is divided into the sum of smaller problems with much less degrees of freedom each, therefore reducing noticeably the computational cost in terms of RAM consumption. RAM usage has been reduced by more than 90% in different probes of metamaterial, and the larger the dimension of the problem, the greater the enhancement. Those results are published as a promising probe of concept of the theory.
