Abstract In this work a broadband Magnetoelectric (ME) dipole antenna for the Global Navigation Satellite System (GNSS) applied to nanosatellites is proposed. The antenna consists of a reflective cavity with open walls c...

We report a discrete dipole approximation approach to analyse the perturbations induced by silver nano-particles on the decay dynamics of a point-like emitter placed in their proximity. Due to the excitation of localized...

Exceptional points (EPs) are the singularities of a non-Hermitian system where the eigenenergies and eigenstates simultaneously coalesce, a topological property that gives rise to a plethora of exotic phenomena. Probing ...

Recently, a three-terminal interface dipole modulation field-effect transistor (IDM FET) memory device has been proposed that leverages electric-field-induced dipole modulation at oxide/oxide interfaces. This device has ...

The significance of bound states in the continuum (BICs) lies in their potential for theoretically infinite quality factors. However, their actual quality factors are limited by imperfections in fabrication, which lead t...

Abstract The extreme positive Indian Ocean Dipole (EXpIOD) peaking in 2023 boreal fall exhibited the strongest variations in sea level and subsurface temperature in the eastern Indian Ocean (IO), and the most equatoriall...

Designing the shape of silicon nanoparticles has been shown to be an effective approach to increasing overlap between electric and magnetic dipole resonances thereby achieving directional scattering and decrease of refle...

The Purcell effect is commonly used to increase the spontaneous emission rate by modifying the local environment of a light emitter. Here, we propose a silicon dielectric cuboid nanoantenna for simultaneously enhancing e...

Abstract This article describes a two-element antenna designed in a Digital Terrestrial Television Broadcasting (DTTB) Multiple Input Multiple Output (MIMO) 2×2 front antenna in the 470 to 700 MHz band. It is based on a...

Landslide are one of the disasters that occur in sloping areas. It occurs very often when the intensity of rainfall is high. Apart from that, it occurs in an area known as a slip area. The slip area is characterized by c...

Abstract Background Dengue fever is hyperendemic in the Lao People’s Democratic Republic (PDR), where transmission is driven by Aedes mosquitoes and influenced by large-scale climatic phenomena, including the El Niño-...

The present work focuses on theoretically research on the spontaneous emission and the energy transfer process between two single optical emitters placed close to a graphene coated wire. The localized surface plasmons (L...

Light-matter interactions at the nanoscale constitute a fundamental ingredient for engineering applications in nanophotonics and quantum optics. In this regard, Mie resonances supported by high-refractive index dielectri...

We examine the quantum dynamics of both a single spin- J particle and a pair of spin- J particles in the presence of static and rotating magnetic fields, which can be important for qudit-based quantum technologies. Notab...

ABSTRACT Antiferroelectrics (AFEs) with typical reversible electrically antipolar‐polar phase transformation have attracted tremendous attention for assembling electronic devices. As a thriving part of the family, mole...

Abstract Radio-Frequency Identification (RFID) is one of the leading enabling technologies of the Internet of Things (IoT) at low cost and high granularity scenarios. The cost of implementing IoT applications concerns th...

Abstract A novel multifunctional bi-anisotropic omega metasurface (MS) that simultaneously supports polarization transformation in both reflection and transmission modes, as well as narrow bandpass transmission functiona...

Context. Silver is a key tracer of the weak r-process in late-type stars. However, when the assumption of local thermodynamic equilibrium is relaxed, accurate abundance determinations become even more sensitive to comple...

We study the Schrödinger equation with 1/r^{3} and attractive 1/r^{2} potentials. Using the quantum defect theory, we obtain analytical solutions for both repulsive and attractive 1/r^{3} interactions. The obtained dis...

We present a comprehensive study of the pulsating primary component of the long-period binary system RY Lep. The spectral energy distribution and the absence of detectable lines indicate that the companion is likely a w...

We study the collective photon decay of multiple quantum emitters embedded in a thin high-index dielectric layer such as hexagonal boron nitride (hBN), with and without a metal substrate. We first explore the significant...

A natural composite Higgs demands the presence of light resonances at the TeV scale that, in general, are in conflict with bounds from flavor and CP violation. We propose a composite model with a Froggatt-Nielsen mechani...

The dipole-dominated magnetic fields of Jupiter and Saturn provide evidence for active dynamos operating within their deep interiors, yet the depth of the convecting dynamo layers remains poorly constrained. While magnet...
