Low reflection multilayered structure containing metamaterial

In this paper a multi-layered structure containing metamaterial is investigated theoretically and numerically. Low reflection and high absorption of electromagnetic waves by the structure are demonstrated at specified frequencies. In the theory, the required equations for the electric and magnetic fields of the incident waves are given in detail. Expressions for the overall reflection and absorption powers of the structure are given in terms of Fresnel coefficients. In the numerical results, the mentioned powers are computed and illustrated as a function of frequency, angle of incidence and metamaterial thickness. The proposed structure could be advantageously used in solar cells.
