  This work is concerned with the propagation of electromagnetic waves in
isotropic chiral media and with the effects produced by a plane boundary
between two such media. In analogy with the phenomena of reflection and
refraction of plane electromagnetic waves in ordinary dielectrics, the
kinematical and dynamical aspects of these phenomena are studied, such as the
intensity of the various wave components and the change in the polarization of
the wave as it crosses the boundary. As a prerequisite of this, we show that
the plane wave solution must be written as a suitable superposition of the
circularly amplitudes on both sides of the interface, we elucidate which is the
appropriate set of conditions that the solution must satisfy at the boundary,
and we set down the minimal, and complete, set of equations that must be solved
for the coefficient amplitudes in order to satisfy the boundary conditions. The
equations are solved explicitly for some particular cases and configurations
(e.g., normal incidence), the salient features of those solutions are analyzed
in some detail, and the general solution to the equations is given as well.
