Microwave terminations, terminations, microwave

Microwave terminations. Microwave terminations are the precise loads required in microwave measurement and calibration systems. Most common among them are matched terminations and variable precession short-circuits. A matched load or a matched termination absorbs all the power incident on it without any reflection.

Influence of Carbon Cap on Self-Diffusion in Silicon …

Self-diffusion of carbon (12C and 13C) and silicon (28Si and 30Si) in 4H silicon carbide has been investigated by utilizing a structure containing an isotope purified 4H-28Si12C epitaxial layer grown on an n-type (0001) 4H-SiC substrate, and finally covered by a carbon capping layer (C-cap). The 13C and 30Si isotope profiles were monitored using secondary ion mass spectrometry (SIMS) following

Mohs scale of mineral hardness - Wikipedia

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material.. The scale was created in 1822 by German geologist and mineralogist Friedrich Mohs; it is one of several definitions of hardness in materials science, some of which are more
