Forward and backward leaky wave radiation with large effective aperture from an electronically tunable surface," IEEE Trans.
2(a)), it starts to operate as a leaky wave antenna whose main angle of elevation can be calculated by the following expression [13, 25]:
Figure 1 shows the 3-D geometry of the proposed leaky wave slot antenna array.
A leaky wave antenna is substantially a waveguide-type structure that leaks out power all along its length due to the existence of a fast travelling wave.
The active radiometry method has also helped in the research of slotted lines, to detect leaky waves predicted in theory, but impossible to detect with CW probing.
r] of the leaky wave radiating from the TL with double periodically loaded inductances and capacitances can be obtained from
However, the microstrip leaky wave only radiates efficiently over a fixed bandwidth, which, in practice, limits maximum scanning.

The proposed antenna technology is based on a recent breakthrough that I pioneered: micro-lenses excited by leaky waves with seamless integration in silicon technology.
45) may contain singularities, and they can be divided into three categories that respectively correspond to three different types of wave front arrivals: 1) The body waves relevant to the regular reflected rays which are determined from the singularities of [partial][phi]/[partial]y = 0,2) The interface waves, including Rayleigh surface waves, Stoneley interface waves, and the other possible leaky waves, which are determined from the singularities of [[DELTA].

In this analysis, the resonance gain phenomenon is modeled based on the TE and TM leaky waves excited in the dielectric layers, which are explicit functions of the transverse dimensions of the layers.
