Abstract

It has been studied theoretically about the phenomenon of electromagnetic wave propagation, including the reflection and refraction events that affect a material that has permittivity (&#949-) and permeability (&#956-), both of which are negative (metamaterial). The metamaterial being studied is a combination of material with negative permittivity (&#949-), namely Wiremesh Structure (WS) and material with negative permeability (&#956-), namely Split Ring Resonator (SRR). In this case negative permittivity (&#949-) and negative permeability (&#956-) are a function of the frequency (&#969-) which can be plotted on a graph to make it easier to get the negative interval of the two materials. The propagation of electromagnetic waves on metamaterials certainly has new consequences for Maxwell^s equations. In addition, reflection and refraction on metamaterials produce modifications to well-established physical laws, such as Snell^s law and Fresnel^s law. From these two laws, quantitative information is obtained regarding the reflection coefficient (r), transmission coefficient (t), reflectance (R), and transmittance (T).
