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

Electronics 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 ...

Anomalous Reflection From a Phase Gradient Metasurface With Arbitrary Incident Angle

IEEE 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.

Emergent Gravity from Noncommutative Spacetime [PDF]

, 2006
We showed before that self-dual electromagnetism in noncommutative (NC) spacetime is equivalent to self-dual Einstein gravity. This result implies a striking picture about gravity: Gravity can emerge from electromagnetism in NC spacetime. Gravity is then

Electromagnetism in terms of quantum measurements [PDF]

, 2015
We consider the question whether electromagnetism can be derived from quantum physics of measurements. It turns out that this is possible, both for quantum and classical electromagnetism, if we use more recent innovations such as smearing of observables ...

Properties of Fiber Bragg Grating in CYTOP Fiber Response to Temperature, Humidity, and Strain Using Factorial Design

Sensors, 2022
The characteristics of fiber Bragg grating (FBG) in cyclic transparent fluoropolymer (CYTOP) optical fiber have attracted more and more attention in recent years.

Electromagnetic radiation [PDF]

British Medical Bulletin, 2003
Electromagnetic fields (EMF) are ubiquitous in modern society. It is well known that exposure to strong fields can result in acute effects, such as burns; the mechanisms behind such effects are well established. There is, however, also a concern that long-term exposure to weak fields might have health effects due to an as-yet unknown mechanism. Because

Knotted solutions for linear and nonlinear theories: Electromagnetism and fluid dynamics

Physics Letters B, 2017
We examine knotted solutions, the most simple of which is the “Hopfion”, from the point of view of relations between electromagnetism and ideal fluid dynamics.

Generalized Electromagnetism of Subdimensional Particles: A Spin Liquid Story [PDF]

, 2017
It has recently been shown that there exists a class of stable gapless spin liquids in 3+1 dimensions described by higher rank tensor U(1) gauge fields, giving rise to an emergent tensor electromagnetism.
