Abstract

Pursuant to the well-known theory of electromagnetic waves propagation in isotropic and anisotropic crystals, rigorous calculation of beam propagation in a system consisting of several anisotropic crystals, results in cumbersome expressions that are not suitable for engineering calculations and do not provide the possibility to study general properties of the two-component crystal-optical lenses. The authors developed an effective method of calculating propagation of electromagnetic waves through the two-component crystal-optical lenses based on uniaxial Iceland spar crystals with different orientations of the optical axes of the crystals in the lens components. Using a narrow beam method (paraxial approximation), the authors obtained an expression describing propagation of electromagnetic waves at the output of the two-component crystal-optical lenses. Based on the developed technique, propagation of electromagnetic waves through each section of crystal-optical lenses was calculated; the authors obtained expressions that are suitable for the analysis of properties in these systems as well as for engineering calculations. The paper presents a comprehensive experimental study of crystal-optical lenses in a split mode of electromagnetic waves at the output of crystal-optical lenses. Research results showed significant agreement between the results of calculations by formulas and experimental data.
