Monolithic High Voltage Impulse Amplifier Using HBT
SUMMARY Lehigh University has developed a method for circuit design for amplifying short impulses using monolithic HBT technology. HBT has the desirable characteristics of high transit frequency (fT) and breakdown voltage for the generation of high power at radio and microwave frequencies. In normal operation the generated power is lower than e...

EM Wave Slow Down Device (Technology #: 072808-01)
SUMMARY Lehigh University has developed and prototyped a device for slowing down and stopping electromagnetic (EM) waves and then, in a controlled manner, accelerating or restarting them again. It allows controlling the speed of light individually for various frequencies, effectively creating a “rainbow trapping device.” The approach ...
