Localization of leaky guided waves
Physica A: Statistical Mechanics and its Applications, 1989A general transfer matrix approach for the propagation of guided waves in presence of inhomogeneities or “scatterers” is presented. It particularly addresses the problem of the coupling with radiation modes leading to a leakage of the guided wave to the surrounding bulk medium at each scattering.

Graphene terahertz leaky-wave antennas
2019In this chapter, we focus on the recent developments made in the context of graphene THz antennas, especially those exploiting the graphene field effect to reconfigure their radiating features. To this purpose, we first review the electronic properties of graphene in the THz range from both a physical and an engineering perspective.

The substrate integrated waveguide can easily be integrated with planar microwave circuits. Antennas designed on this transmission line have a planar structure, and can be fabricated by a standard PCB technology, so they are suitable for mass production.

Lumped Element and Leaky-Wave Antennas for Millimeter Waves.
1984Abstract : Some millimeter wave antennas can be scaled from their microwave frequency counterparts, but others cannot because of two main problems; the small wavelengths, which require small waveguide dimensions and pose fabrication difficulties, and higher metal loss.

The main radiation mechanism in a leaky wave antenna is a travelling wave in a guided structure. The main characteristics of a leaky wave antenna are: light weight, easy to fabricate. Leaky wave antennas have been in use since the 1940s. In this thesis, a portable and powerful leaky-wave antenna is designed, implemented, and demonstrated for scanning ...
