Modeling of a Waveguide Polarizer with a Wedge-Shaped Magnetic Wall
P. 1–5.
The significance of the polarization state of propagating electromagnetic waves is profound in domains such as radiolocation, radio and satellite communications, and related scientific and technological disciplines. The contemporary demand is for increasingly efficient waveguide polarizers with simplified structure and improved mass-dimensional characteristics. This study introduces a model for a waveguide polarizer employing a rectangular WR-284 waveguide section, within which is a wedge-shaped magnetic wall constituted of a mushroom-shaped metamaterial. Computational simulations provided radiation patterns from the open end of the waveguide structure across a frequency range spanning 400 MHz to 5 GHz, illustrating the change of the electromagnetic wave polarization based on the selected frequency.

Semiconductor lead halide perovskites have attracted significant attention for various applications. Understanding the impact of material composition on optical properties is essential for optimizing device performance. Here, we performed magneto-optical spectroscopy on high-quality bulk CsPbBr3, MAPbBr3, and MAPbI3 single crystals under magnetic fields of up to 30 T. The results revealed distinctive excitonic responses to the magnetic ...

Affective political polarization is comprehensively considered in combination of its emotional, behavioral and cognitive aspects. They manifest themselves in the differences between an individual's attitude towards politically like-minded people (the in-group) and opponents (the out-group), includingemotions experienced, willingness to cooperate, and a tendency to attribute positive or negativequalities.
Particular attention is paid to the problem of differences between the intensity of manifestations of affective political polarization in the online environment compared to traditional forms of communication. Most contemporary researchers predict a higher level of polarization ...

The electrochemical behavior of the as-cast Al0.5CoCrFeNiCuxAgy (x = 0.25, 0.5; y = 0, 0.1) high-entropy alloys (HEAs) in a 0.5M H2SO4 solution was studied. Polarization measurements were carried out in a standard three-electrode electrochemical cell at room temperature using a platinum counter electrode and a saturated silver chloride reference electrode. For Al0.5CoCrFeNiCu0.5 and Al0.5CoCrFeNiCu0.5Ag0.1, ...

Let U be the unitriangular group over a finite field. We consider an interesting class of irreducible complex characters of U, so-called characters of depth 2. This is a next natural step after characters of maximal and submaximal dimension, whose description is already known. We explicitly describe the support of a character of depth 2 by a system ...

This article examines two opposing media consumption trends—news avoidance and doomscrolling—through the lens of media environment and societal fragmentation. News avoidance refers to the conscious limitation of economic or socio-political content consumption to maintain emotional well-being, while doomscrolling is defined as compulsive and excessive attention to negative news. The study is based on 91 semi-structured ...

In two-dimensional (2D) materials, breaking the inversion symmetry plays an important role in valleytronics. Ferrovalley (FV) materials can achieve spontaneous valley polarization (VP) without additional modulation due to the magnetic exchange interaction and strong spin–orbit coupling. Using first-principles calculations, we predict a new 2D material, Janus FeClSH, which exhibits a large spontaneous VP. This monolayer ...

Value polarization is one of the key factors in societal development. This research focuses on whether opinions concerning gender roles in the domestic and public spheres are polarized in European societies, a topic still under-investigated. Based on the fifth wave of European Values Study data (2017–2020), the study shows that gender role attitudes in the ...

The phase- and energy-resolved polarization measurements of accreting X-ray pulsars (XRPs) allow us to test different theoretical models of their emission, and they also provide an avenue to determine the emission region geometry. We present the results of the observations of the XRP GX 301−2 performed with the Imaging X-ray Polarimetry Explorer (IXPE). A persistent ...

Two agents announce the state they consider most likely infinitely many times. A small departure from common belief in rationality can have a severe impact on the belief about the state and on the behavior of an extremist: while initial periods of disagreement produce a temporary convergence of beliefs, prolonged disagreement induces reversion towards the ...

We model costly, strategic voting in an electorate divided between a single pro-incumbent and multiple pro-opposition groups, and study the effect of the homogeneity of preferences within the opposition electorate on voter turnout. If each opposition group is represented by a separate candidate, there is a free-rider effect: the opposition turnout is lower if different ...
