Resonant State Spectral expansions including bound-state contributions [PDF]
EPJ Web of Conferences, 2023 Extensions of the Resonant State or (Quasi-normal mode) formalism are shown to permit unified descriptions of the true ’bound’ states within the framework of the ’leaky’ mode formulation of basis sets.

IEEE Access, 2023 A rectangular metallic leaky waveguide loaded with liquid crystals (LC) and operating in its fundamental TE mode at 1 THz is proposed to mitigate the well-known trade-off between directivity and tunable angular range of dynamic beamscanning antennas. The

Analysis and Design of Tunable THz 1-D Leaky-Wave Antennas Based on Nematic Liquid Crystals
Applied Sciences, 2022 The tunable properties of nematic liquid crystals (NLC) are here exploited in a peculiar leaky waveguide with artificial magnetic conductors as the lateral walls, a bottom metal ground plane, and a homogenized metasurface on top to obtain dynamic ...

Backside emission leaky-mode modulators
Optics Express, 2017 We report on an advancement to leaky-mode modulators that allows for backside emission from the device. This is accomplished by adding a high spatial frequency surface relief grating (~300 nm period) to the backside of the modulator. The outcome being a theoretical arbitrary increase in usable output aperture, at the cost of angular deflection.

High-efficiency wide-band metal-dielectric resonant grating for 20 fs pulse compression [PDF]
Journal of the European Optical Society-Rapid Publications, 2007 More than 95% average efficiency TE-polarisation diffraction over a 200 nm wavelength range centred at 800 nm is obtained by a metal-dielectric grating structure with non-corrugated mirror.

Characterization of Anisotropic Leaky Mode Modulators for Holovideo [PDF]
Journal of Visualized Experiments, 2016 Holovideo displays are based on light-bending spatial light modulators. One such spatial light modulator is the anisotropic leaky mode modulator. This modulator is particularly well suited for holographic video experimentation as it is relatively simple and inexpensive to fabricate.

The Astrophysical Journal Letters, 2023 Magnetohydrodynamic (MHD) waves are often invoked to interpret quasiperiodic pulsations (QPPs) in solar flares. We study the response of a straight flare loop to a kink-like velocity perturbation using three-dimensional MHD simulations and forward model ...
