He received a Research Corporation grant in 1958 to for investigations of the microwave spectra of radicals and molecules.

Traditionally, the FCC has assigned microwave spectrum based on historic patterns of need and through the application/request process.

It scanned through the microwave spectrum from 1.400 to 1.720 gigahertz in eight hops, with two seconds of observation per hop.

Recently the Federal Communications Commission approved the use of the microwave spectrum between 22 and 29 gigahertz for radar systems in vehicles.

It triggered an international effort to measure and analyze the microwave spectrum of Venus.

On the other hand, microwave spectra are usually measured in Gigahertz.

The microwave spectrum is employed by radar, cell phones, and wireless Internet.

First, since its effectiveness was only in the microwave spectrum the small object is somewhat invisible only at microwave frequencies.

The absorption at this frequency was the first microwave spectrum to be observed.

Up close, in the microwave spectrum, it was a quilt of hot and cold spots.
