  • Abstract
    The Finite-Difference Time-Domain (FDTD) method is used to simulate the electromagnetic problem of transmission through a metallic screen with slots of sizes and spacing that were chosen using the spatially shifted beam approach to achieve subwavelength focusing. The challenges related with the modeling of such sub-wavelength focusing meta-screens are demonstrated via the study of numerical convergence.
