This paper presents the electromagnetic fleld expressions for 3D cassegrain system embedded in a bi-isotropic chiral medium. Mathematical formulation of Maslov is used to flnd the fleld expressions in the focal region. Efiect of chirality (both the week and strong) on focal region flelds is analyzed. It is seen that when the chirality efiect is weak (i.e., • 1), one mode travels with PPV and the other mode travels with negative phase velocity (NPV). The line plots are given to show the behavior of flelds in the focal plane of 3D cassegrain system by changing the chirality parameter (•).
