A Subcell Finite-Difference Time-Domain Implementation for Narrow Slots on Conductive Panels

open access: yesApplied Sciences, 2023
Efficiently modeling thin features using the finite-difference time-domain (FDTD) method involves a considerable reduction in the spatial mesh size. However, in real-world scenarios, such reductions can lead to unaffordable memory and CPU requirements ...

The implementation of wideband 90° hybrids on non‐optimal substrates

open access: yesElectronics Letters, 2022
A new technique to implement wideband 90° hybrid coupling profiles on non‐optimal substrate configurations is presented. The technique uses an impedance taper over the whole length of the hybrid to remove the restriction of a substrate defined maximum ...

Surface Plasmon Resonance sensor based on a D-shaped photonic crystal fiber with a bimetallic layer [PDF]

open access: yesEPJ Web of Conferences, 2020
The investigation of a D-shaped photonic crystal fiber sensor with a bimetallic layer for operation at the visible and infrared spectra is presented. The bimetallic layer is composed by silver and gold slabs deposited adjacently on the flat face of the ...

Anomalous Reflection From a Phase Gradient Metasurface With Arbitrary Incident Angle

open access: yesIEEE Access, 2023
A planar phase gradient metasurface (PGM) with phase gradients in two in-plane directions will introduce two additional wave vectors to the reflected wave vector.

Histories electromagnetism [PDF]

open access: yesJournal of Mathematical Physics, 2004
Working within the HPO (History Projection Operator) Consistent Histories formalism, we follow the work of Savvidou on (scalar) field theory [J. Math. Phys. 43, 3053 (2002)] and that of Savvidou and Anastopoulos on (first-class) constrained systems [Class. Quantum Gravt.

Electromagnetic circuits

open access: yesNetworks & Heterogeneous Media, 2010
The electromagnetic analog of an elastic spring-mass network is constructed. These electromagnetic circuits offer the promise of manipulating electromagnetic fields in new ways, and linear electrical circuits correspond to a subclass of them. They consist of thin triangular magnetic components joined at the edges by cylindrical dielectric components ...

New theories on electromagnetism and on light and colors

open access: yes, 2021
Completely new theories on two fields. 1) Electromagnetism 2) Light and colors The theories are based on very simple and very easily reproducible experiments, some of them, although simple, still very impressive and yet not known.
