Characteristics of a transverse slot in the upper plate of a nonradiative dielectric guide operating in the dominant LSE/sub 00/ mode have been analyzed. A fundamental radiation phenomenon due to the open property of the guiding structure is observed

Radiation region for open guiding structures is known to be further divided into antenna- and reactive-mode regions, and there is no clear cutoff point defined between the two regions. For a leaky-wave antenna, it is crucial that the antenna is desig

A new leaky nonradiative dielectric guide with a double-layer dielectric slab is investigated in this paper by combining a multimode network theory with a mode-matching method. Numerical results show that proper selection of the permittivities can va
