Abstract :
The authors present a theoretical study of antiresonant waveguides, in cylindrical and planar geometry, using leaky mode solutions of the vector wave equation. General analytical expressions are derived to describe the attenuation coefficients of TE, TM, HE, and EH modes of multilayered leaky waveguides, taking into account material absorption. Results obtained with these expressions are compared to numerical solutions and found to be accurate when the leakage loss is low.
