Leaky modes of a left-handed slab [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 Using complex plane analysis we show that left-handed slab may support either leaky slab waves, which are backward because of negative refraction, or leaky surface waves, which are backward or forward depending on the propagation direction of the surface

Mixer-Duplexer-Antenna Leaky-Wave System Based on Periodic Space-Time Modulation
, 2016 We present a mixer-duplexer-antenna leaky-wave system based on periodic space-time modulation. This system operates as a full transceiver, where the upconversion and downconversion mixing operations are accomplished via space-time transitions, the ...

Guiding and Leakage Dispersion Characteristic of TM01Mode in a Circular Dielectric Rod
International Journal of Antennas and Propagation, 2022 Open dielectric waveguide structures such as circular dielectric rods can be used as antennas by leaking energy in the transverse direction or as guiding structures with low loss in integrated circuits at different frequency ranges.

Pencil-Beam Single-point-fed Dirac Leaky-Wave Antenna on a Transmission-Line Grid
, 2016 Leaky-wave antennas (LWAs) are widely used as single-point-fed linear antenna arrays. The extension of LWAs to 2D implies that they can be used as single-point-fed 2D antenna arrays without requiring a complex feeding network.

Leaky Horns: A New Paradigm of Developing Electromagnetic Horns Based on Leaky-Wave Structures
Electromagnetic ScienceMore than one-century history of microwaves has witnessed two seemingly unrelated developments of leaky-wave and horn antennas. While conventional horns cannot be made free from phase error even though the optimum horn criterion is adopted, this problem ...

Radiative anti-parity-time plasmonics
Nature Communications, 2022 The parity-time symmetry has led to exotic phenomena and fruitful applications in optical systems. In this paper, the authors propose a leaky-wave-enabled anti-parity-time design and realize space-wave harnessing.

First arriving signals in layered waveguides. An approach based on dispersion diagrams
, 2016 The first arriving signal (FAS) in a layered waveguide is investigated. It is well known that the velocity of such a signal is close to the velocity of the fastest medium in the waveguide, and it may be bigger than the fastest group velocity given by the
