In this paper, a theoretical investigation of electromag- netic fleld transmission through dielectric plano convex lens placed in chiral medium is analyzed. The chiral medium is described electro- magnetically by the constitutive relations D = †(E + ∞r £ E) and B = "(H + ∞r £ H). Transmission's coe-cients for chiral-dielectric and dielectric-chiral interfaces are derived analytically. The analytical fleld expressions for right circularly polarized (RCP) and left circularly polarized (LCP) waves are obtained using Maslov's method. Numerical computations are made for the fleld patterns around the caustic region using Mathcad software to observe the efiect of chirality parameter.
