We propose a series of integrated Bragg grating filters with performance enhancement via the concept effective medium. The bandstop are built in high-resistivity silicon wafer and operated over WR-3.4 band (220–330 GHz) in-plane polarization. proposed designs use an additional degree freedom controlling refractive index so as to fully potential structures. As result, high insertion loss typical...

Production of aluminum alloy clad strips requires many processes, and a reduction in the number processes has long been demanded. A method to cast directly from molten metal using twin roll caster with copper rolls is proposed this work. Two types casters were designed tested. One was vertical-type tandem other equipped scraper. The casting conducted an oxidizing atmosphere. at speeds higher th...
