The EIM was introduced at first. By solving the scalar wave equation within cladding of TIR-PCF, the fundamental space-filling mode and the effective index of the cladding were calculated. The logical effective radius was selected, and the propagation properties of TIR-PCF were discussed with the classical theory of step-index fiber.
