Enhanced luminescent solar concentrator efficiency by Foster resonance energy transfer in a tunable six-dye absorber
(Wiley, 2021-06)
Luminescent solar concentrators (LSCs) collect and concentrate the solar irra-diation to generate electricity through the photovoltaic effect. LSCs haveattracted attention due to their concentration factors, their ability ...

Cross-Polarization Control in FSSs by Means of an Equivalent Circuit Approach
(IEEE Computer Society, 2021)
This paper presents an efficient equivalent circuit approach (ECA), based on a Floquet modal expansion, for the study of the co- and cross-polarization in frequency selective surfaces (FSS) formed by periodic arrays of ...

Breather stripes and radial breathers of the two-dimensional sine-Gordon equation
(Elsevier, 2021-03)
We revisit the problem of transverse instability of a 2D breather stripe of the sine-Gordon (sG) equation. A numerically computed Floquet spectrum of the stripe is compared to ana- lytical predictions developed by means ...

Reaction-diffusion spatial modeling of COVID-19: Greece and Andalusia as case examples
(American Physical Society, 2021-08)
We examine the spatial modeling of the outbreak of COVID-19 in two regions: the autonomous community of Andalusia in Spain and the mainland of Greece. We start with a zero-dimensional (0D; ordinary-differential-equation-level) ...

Tailoring Crystalline Structure of Titanium Oxide Films for Optical Applications Using Non-Biased Filtered Cathodic Vacuum Arc Deposition at Room Temperature
(MDPI, 2021-02)
Titanium oxide films were deposited at room temperature and with no applied bias using a filtered cathodic vacuum arc (FCVA) system in a reactive oxygen environment. The dependence of film growth on two process parameters, ...

Exploring the potentials of the multi-modal equivalent circuit approach for stacks of 2-D aperture arrays
(IEEE Computer Society, 2021)
Many frequency-selective surface (FSS) structures are based on the use of a single periodic array of slot/apertures in a conducting sheet embedded in a layered medium. However, it is well known that stacking several ...

Study of forward and backward modes in double-sided dielectric-filled corrugated waveguides
(MDPI, 2021)
This work studies the propagation characteristics of a rectangular waveguide with aligned/ misaligned double-sided dielectric-filled metallic corrugations. Two modes are found to propagate in the proposed double-sided ...

On the Benefits of Glide Symmetries for Microwave Devices
(IEEE Computer Society, 2021)
The presence of glide symmetries in periodic structures can introduce beneficial modifications in their electromagnetic properties. The difference between glide and non-glide periodic structures is due to the distinctive ...

Transport and dispersion of tritium from the radioactive water of the Fukushima Daiichi nuclear plant
(ELSEVIER, 2021)
Japan recently announced plans to discharge over 1.2 million tons of radioactive water from the Fukushima Daiichi Nuclear Power Plant (FDNPP) into the Pacific Ocean. The contaminated water can poses a threat to marine ...
