Researchers at Purdue University have developed a triggering system for electric micropropulsion systems. The system incorporates a low current surface flashover and is capable of operating reliably for a large number of triggering events. This device would be used in micropropulsion systems but can.....

High Impedance Surfaces (HIS) are one of the breakthroughs that emerged in the modern antenna design area in 1999. HISs are ideal candidates as antenna ground planes because of their near perfect magnetic ground conductor (PMC) behavior at particular ranges. However, current rectangular designs have.....
