Optical materials characterization

, 1977
Abstract : The refractive index of a sample of hot-forged CaF2 was measured from 0.25 micrometers to 8.0 micrometers by means of the minimum-deviation method on a precision spectrometer. Data were obtained near 20 C and 34 C. Each data set was fitted to a three-term Sellmeier-type dispersion equation, which permits interpolation of refractive index as ...

Classification and characterization of electromagnetic materials [PDF]

Scientific Reports, 2020
AbstractIn this paper, we present an efficient method to classify complex electromagnetic materials. This method is based on the directional interaction of incident circularly polarized waves with the materials being tested. The presented method relies on an algorithm that classifies the test materials to one of the following categories: isotropic ...

Strengthening Al-Zn-Mg Alloys via Ultra-Fine Lamella Structures Containing a High Density of Dislocations and Clusters

Metals, 2019
A new method of thermo-mechanical processing has been designed by introducing pre-aging before general cold rolling for an Al-Zn-Mg alloy. This process results in an increase of 200 MPa in yield strength compared to that of the peak-aged samples.

Surface potential imaging and characterizations of a GaN p-n junction with Kelvin probe force microscopy

AIP Advances, 2020
We applied Kelvin probe force microscopy (KPFM) to characterize the p-n junction grown on hydride vapor-phase epitaxy GaN wafers with three different doses of the p-type dopant Mg.

Design and Construction of a Brain-Like Computer: A New Class of Frequency-Fractal Computing Using Wireless Communication in a Supramolecular Organic, Inorganic System

Information, 2014
Here, we introduce a new class of computer which does not use any circuit or logic gate. In fact, no program needs to be written: it learns by itself and writes its own program to solve a problem.
