Abstract : We have investigated and determined how the tensor properties of an impedance surface can be shaped to control and steer surface waves in a very general way, all the while preserving phase information. Two findings made this possible. First, it was discovered through eigenvalue analysis that a TM or TE surface bound wave tends to favor ...

Impedance modulation patterns for artificial-impedance-surface antennas
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013Artificial impedance surface antennas (AISAs) radiate by leaking surface waves from a spatially-modulated artificial impedance surface (AIS) whose modulation is designed to produce a preferred radiation pattern and polarization. Using the AISA radiation integral, a simple equation is obtained that quickly computes the modulation pattern for an AISA ...

On focusing of surface waves on impedance guiding surfaces
Journal of Communications Technology and Electronics, 2017The process of focusing of surface electromagnetic waves on impedance guiding surfaces is considered in the ray approximation with the help of a 2D model of a plane surface. An estimate of the influence of the wave properties of the field on this process is given.
