Abstract Using a combination of finite element numerical simulation and experimental verification, the honeycomb structure with different parameters negative Poisson’s ratio is compressed at uniform speed. The influence angle parameter θ , size h thickness t on energy absorption whole studied, main factors influencing are discussed. results show that larger concave angle, smaller cell, better o...

The Bremmer coupling series solution of the wave equation, in generally inhomogeneous media, requires the introduction of pseudo-differential operators. In this paper, in two dimensions, uniform asymptotic expansions of the Schwartz kernels of these operators are derived. Also, we derive a uniform asymptotic expansion of the one-way propagator appearing in the series. We focus on designing clos...

Non-uniform irradiance patterns over Multi-Junction Cells gives rise to power losses, especially when considering spectral irradiance distributions over different junctions. Thermal effects on Silicone-on-Glass lenses affect spectral irradiance distributions. A new Photovoltaic Concentrator (CPV), formed by nine optical channels, each one with a Köhler configuration, has been designed to overco...

This paper investigates a Modified Uniform Triangular Array (MUTA) to support online space-time MIMO-CDMA location based services with full azimuthal coverage via JADE-MUSIC algorithm. A new space-time lifting preprocessing (STLP) scheme is introduced as a decorrelating process of coherent signals through the dense/NLOS multipath MIMO channel before applying the JADE-MUSIC estimator. UniformH-A...

Micro and nanostructured surfaces have broad applications including heat transfer enhancement in phase-change systems and liquid manipulation in microfluidic devices. While significant efforts have focused on fabricating static micro/nanostructured arrays, uniform arrays that can be dynamically tuned have not yet been demonstrated. In this work, we present a novel fabrication process for magnet...

A novel scheme is proposed for direction finding with uniform rectangular planar array. First, the characteristics of noncircular signals and Euler's formula are exploited to construct a new real-valued rectangular array data. Then, the rotational invariance relations for real-valued signal space are depicted in a new way. Finally the real-valued propagator method is utilized to estimate the pa...

We describe a dual-mirror wide angle optical design, which removes the radial distortion associated with traditional all-sky optics for a chosen altitude. The wide angle mirror system provides a transform of the sky, for a selected altitude, as if the viewer is situated at the center of the Earth. Other advantages of the system include (1) real time achromatic transform, (2) higher optical gain...
