Title: Michael Gregg Spencer: Innovator in Energy Conversion and Submillimeter Wave Technology
Introduction
Michael Gregg Spencer is a notable inventor based in Washington, DC. He has made significant contributions to the fields of energy conversion and submillimeter wave technology. With a total of 2 patents, Spencer's work reflects his innovative approach to solving complex engineering challenges.
Latest Patents
One of Spencer's latest patents is focused on incandescent light energy conversion with reduced infrared emission. This invention allows for energy conversion among heat or electricity, specifically in incandescent light emission, by utilizing a high band gap semiconductor element. This element is designed to suppress free carrier absorption, making it transparent or reflective to photon energy below the band gap while only emitting photon energy above it. A filament made of lightly 'N' doped 3C-SiC, heated to about 900 degrees Celsius, will incandesce and radiate in the visible range for energies greater than approximately 2 eV, while exhibiting inefficient emission for lower energies.
Another significant patent is for an optically-switched submillimeter-wave oscillator and radiator. This integrated circuit includes an array of N photoconductive switches that are biased across a common voltage source. The design allows for different optical delays to each switch, generating radiation of a submillimeter wave frequency. The circuit is capable of producing radiation frequencies of the order of or greater than 1 Terahertz, making it a remarkable advancement in the field.
