Abstract

The design of a compact quarter-wave plate requires a knowledge of both the phase constants of its split normal modes and those of its dual degenerate coupled modes. It also requires a statement of its scattering matrix. The paper formulates this problem and provides an experimental database for the phase constants of one type of plate using a resonator technique. The normal modes of the device are described in terms of relative effective dielectric constants. These are derived by forming equivalences between the inhomogeneous normal-mode problems and homogeneous equivalent waveguide models. The effective dielectric constants of the normal modes are given separately.
