Abstract

A simple but good alternative way is given to define the antenna-mode and reactive-mode regions for open dielectric guiding structures by means of the concept of complex effective dielectric constant. The attenuation constant is clearly divided for the first time into two separate parts due to cutoff and leakage effect respectively. Simple closed-form expressions are derived to determine the two parts.
