Disorder Effects in One-Dimensionally Periodic Extraordinary Transmission Structures
(MDPI, 2022)
Extraordinary transmission structures show promising capabilities for highly selective filters in both frequency and angle of incidence. However, their realistic response once manufacturing limitations are taken into account ...

Extraordinary Transmission and Radiation from Finite by Infinite Arrays of Slots
(Institute of Electrical and Electronics Engineers, 2020)
In this communication an efficient method of moments (MoM) code is used for the analysis of the extraordinary transmission (EOT) through a periodic array of rectangular slots in a conducting screen, in the case where the ...

Effect of Epsilon-Near-Zero Modes on the Casimir Interaction between Ultrathin Films
(American Physical Society, 2023)
Vacuum fluctuation-induced interactions between macroscopic metallic objects result in an attractive force between them, a phenomenon known as the Casimir effect. This force is the result of both plasmonic and photonic ...

Revealing the underlying mechanisms behind TE extraordinary THz transmission
(Optical Society of America, 2020)
Transmission through seemingly opaque surfaces, so-called extraordinary transmission, provides an exciting platform for strong light–matter interaction, spectroscopy, optical trapping, and color filtering. Much of the ...

Effective-periodicity effects in Fibonacci slot arrays
(American Physical Society, 2021-12-29)
In this Letter, the transmission properties of a nonperiodic array of slots arranged in the form of a Fibonacci sequence are investigated. By arranging the slots in this manner, an additional periodicity can be utilized, ...

Engineering Casimir interactions with epsilon-near-zero materials
(American Physical Society, 2022-06-03)
In this paper, we theoretically demonstrate the tunability of the Casimir force both in sign and magnitude between parallel plates coated with dispersive materials. We show that this force, existing between uncharged plates, ...

Ray-Tracing Model for Generalized Geodesic-Lens Multiple-Beam Antennas
(IEEE, 2023)
Geodesic-lenses are a compelling alternative to traditional planar dielectric lens antennas, as they are low loss and can be manufactured with a simple mechanical design. However, a general approach for the design and ...

On the Excitation of Magnetic Current Surface Waves in Truncated Periodic Arrays of Slots Under Extraordinary Transmission Conditions
(Institute of Electrical and Electronics Engineers, 2020)
In this paper, we explore the excitation of magnetic current surface waves in truncated periodic arrays of slots in a conducting screen. A specialized Method of Moments (MoM) implementation is presented, which makes it ...

Electrically Switchable Casimir Forces Using Transparent Conductive Oxides
(AMER PHYSICAL SOC, 2022)
Casimir forces between charge-neutral bodies originate from quantum vacuum fluctuations of electromagnetic fields, which exhibit a critical dependence on material’s electromagnetic properties. Over the years, in situ ...
