A New Antenna-feedback Scheme to Achieve Emission in a Narrow Beam from Metal-cavity Semiconductor Lasers
SUMMARY The invention is based on a distributed antenna-coupling (feedback) scheme and specially designed distributed feedback (DFB) metallic cavity grating. By ensuring the predesigned phase condition, the mode traveling inside the waveguide is coupled/phase-locked to the mode traveling outside on the top metal, hence establishing a standing-wave...

Tube Launched UAV
SUMMARYLehigh University has designed a few concepts for UAV aircraft, presumably unmanned ditto, launched from a tube such as a grenade launcher, gun, mortar, etc. The aircraft is packed such that it fits inside the tube and then deploys its wings after exiting from the tube. The first concept is a UAV with a “flying wing” configuratio...
