Effect of Ground Plane Deformation on Electrical Performance of Air Microstrip Antennas
This paper covers the variation of electrical performance of air microstrip antennas due to its ground plane deformation. A typical sinusoidal function is utilized to characterize the shape of deformation, based on which different shapes of ground plane ...

Electronic structure of MnSi: The role of electron-electron interactions
We present an experimental study of the electronic structure of MnSi. Using x-ray absorption spectroscopy XAS, x-ray photoemission, and x-ray fluorescence, we provide experimental evidence that MnSi has a mixed valence ground state. We show that self-consistent local density approximation supercell calculations cannot replicate the XAS spectra of MnSi,

Giant enhancement of nonreciprocity in gyrotropic heterostructures
Nonreciprocity is a highly desirable feature in photonic media since it allows for control over the traveling electromagnetic waves, in a way that goes far beyond ordinary filtering.

Miniaturized Wideband CP Antenna Using Hybrid Embedded Metasurface Structure
In this study, a hybrid embedded metasurface (MTS) structure is proposed and applied to realize a miniaturized MTS antenna. In contrast to the conventional periodic rectangular MTS, the proposed MTS structure is formed by hybrid embedded patches composed

Electronic structure of turbostratic graphene [PDF]
We explore the rotational degree of freedom between graphene layers via the simple prototype of the graphene twist bilayer, i.e., two layers rotated by some angle $\theta$.

Antireflection coated semiconductor laser amplifier for Bose-Einstein condensation experiments
We present a slave laser highly suitable for the preparation and detection of 87Rb Bose-Einstein condensates (BEC). A highly anti-reflection coated laser diode serves as an optical amplifier, which requires neither active temperature stabilization nor ...

The inverse finite element method (iFEM) is a novel method for reconstructing the full-field displacement of structures by discrete measurement strain. In practical engineering applications, the accuracy of iFEM is reduced due to the positional offset of

On the Structure of the Electron [PDF]
Usually the electron is described as a mathematical point with charge, mass, spin angular momentum, and electromagnetic field. Because of the unbounded energies this causes mathematical difficulties [1]. These can be avoided by considering a finite radius.
