Large Surface LC -Resonant Metamaterials: From Circuit Model to Modal Theory and Efficient Numerical Methods

We studied the harmonic magnetodynamic behavior (without free space wave propagation) of a resonant surface metamaterial, made of many identical and regularly arranged LC cells. The circuit model gives the exact solution, but it is not numerically efficient for simulating very large structures (e.g., 1000 × 1000 cells giving 106 unknowns with a full 106 × 106 matrix). For the first time, we highli...
