We present computational analysis of optical nanostructures, including but not limited to frequency-selective surfaces, metamaterials, nanoantennas, nanowires, and photonic crystals. A rigorous implementation based on surface integral equations and t

We present resonance-free solutions of scattering problems involving closed conductors using the magnetic field integral equation (MFIE). In the literature, MFIE is often combined with the electric-field integral equation (EFIE) to avoid internal res

The conventional combined-field integral equation (CFIE)using a Galerkin scheme suffers from inaccuracy issues due to the incorrect testing of the identity operator in the magnetic-field integral equation (MFIE). In this contribution, a mixed discret

We present a new method for the reconfiguration of inkjet-printed antennas to make them operate at different frequencies while matching to different impedances other than originally designed. Suitable antennas are modified by replacing conventional g

In this paper, we present design and numerical simulations of nano-cavities for free-space matching in solar cells at optical frequencies. The cavity designs are inspired by the well-known antenna geometries that are commonly used at radio and microw

An infinitely smooth parametrical representation with derivatives of all orders is used, resulting into exponentially converging solutions of magnetic field integral equation (MFIE) in 2D either for TM or TE polarized excitations. A version of super
