This work is concerned with the propagation of electromagnetic waves inisotropic chiral media and with the effects produced by a plane boundarybetween two such media. In analogy with the phenomena of reflection andrefraction of plane electromagnetic waves in ordinary dielectrics, thekinematical and dynamical aspects of these phenomena are studied, such as theintensity of the various wave components and the change in the polarization ofthe wave as it crosses the boundary. As a prerequisite of this, we show thatthe plane wave solution must be written as a suitable superposition of thecircularly amplitudes on both sides of the interface, we elucidate which is theappropriate 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 solvedfor the coefficient amplitudes in order to satisfy the boundary conditions. Theequations are solved explicitly for some particular cases and configurations(e.g., normal incidence), the salient features of those solutions are analyzedin some detail, and the general solution to the equations is given as well.
