Physical optics and full wave simulations of transmission of electromagnetic fields through electrically large planar meta-sheets

Metamaterials bring new opportunities to radome design, including an improved transmission over a broader range of antenna scan angles, tailorable and reconfigurable frequency bands, polarization transformations, one-way transmission and switching ability. However, the smallness of the unit cell introduces additional complications in full wave numerical simulations, requiring a very fine sampling over an electrically large area of the radome. This paper describes the results of numerical simulations of electromagnetic transmission through planar meta-sheets (infinite and circularly shaped) by using a full wave simulator and a physical optics solution
