Hollow core anti-resonant fibers (HCAR) exploit the resonant structure of the cladding to decrease the propagation loss at specific transmission windows located in between resonance wavelengths. HCAR loss is usually computed by numerical methods such as finite elements or estimated by analytical formulas. Here, the semi-analytical method based on solution of the nonlinear dispersion equation is presented and discussed. The method employs the theory of propagation of electromagnetic waves in cylindrically-layered media and it is fully vectorial. Its reliability and efficiency is tested by comparison with results of numerical simulations of the HCAR structure using modal analysis in COMSOL
