Comparing Planar Resonant Periodic Structures

The article outlines and compares the outcomes obtained from the numerical modelling of planar resonator structures designed for THz frequencies. In order to achieve a response in the THz region of the electromagnetic field, we employ three types of dot-like structures, namely, squares, circles, and dipoles, to form the desired arrays. The numerical analysis respects the material properties, which have to comply with the working frequencies in the THz region.
