Figure 3. Full-wave simulation results of electric fields inside and outside the metamaterials.

The calculations are performed for the circular continuous-material and drilled-hole metamaterial plates under the excitation of a 2D point source at 10 GHz. Both plates have a radius of 62.5 mm and a thickness of 3 mm, and are placed in a planar waveguide. Hence, the simulations can be performed using 2D models (TE polarization).
