The numerical simulation of the interaction of a plane electromagnetic wave with a metasurface consisting of split-ring resonator

Results of the numerical simulation of the interaction of a plane electromagnetic wave with a metasurface consisting of split-ring resonator (SRR) unit cells of a resonant frequency f = 2.5 GHz (located, among others, in the LTE/WiFi band present in the electromagnetic environment) are presented in this paper. The numerical calculations were performed using the CST Studio solver dedicated to solving electromagnetic problems The simulations of the interaction of the plane electromagnetic wave with the SRR metasurface were performed for a distance between the SRR metamaterial unit cells equal to lambda/20, where lambda = 119.916 mm (corresponding to f = 2.5 GHz. A new visualization approach has been introduced in this work to present effects of the interaction of the electromagnetic radiation with the metamaterial structure. The calculations of the absorption, reflection and transmission coefficients of the incident plane electromagnetic wave showed that the SRR metasurface strongly reflects the plane electromagnetic wave at a frequency equal to the magnetic resonance frequency of the SRR metasurface. These calculations were confirmed by visualizing the phenomenon of plane electromagnetic wave reflection from the SRR metasurface. The numerical method used in this work seems to be attractive for the visualization of the electromagnetic phenomena in metamaterials.

Automated summary

This paper presents the numerical simulation results of the interaction between a plane electromagnetic wave and a metasurface consisting of split-ring resonator (SRR) unit cells with a resonant frequency f = 2.5 GHz. The calculations show that the SRR metasurface strongly reflects the plane electromagnetic wave at the magnetic resonance frequency of the SRR metasurface, and this phenomenon was confirmed through visualization. The numerical method used in this study appears to be attractive for visualizing electromagnetic phenomena in metamaterials.
