Query: Near-Perfect Conversion of a Propagating Plane Wave into a Surface Wave
  Using Metasurfaces   In this paper, theoretical and numerical studies of perfect/nearly-perfect
conversion of a plane wave into a surface wave are presented. The problem of
determining the electromagnetic properties of an inhomogeneous lossless
boundary which would fully transform an incident plane wave into a surface wave
propagating along the boundary is considered. An approximate field solution
which produces a slowly growing surface wave and satisfies the energy
conservation law is discussed and numerically demonstrated. The results of the
study are of great importance for the future development of such devices as
perfect leaky-wave antennas and can potentially lead to many novel
applications.
