The Microwave-Drill [PDF]

IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2002
We present a drilling method that is based on the phenomenon of local hot spot generation by near-field microwave radiation. The microwave drill is implemented by a coaxial near-field radiator fed by a conventional microwave source. The near-field radiator induces the microwave energy into a small volume in the drilled material under its surface, and a

Hierarchical Metamaterials for Multispectral Camouflage of Infrared and Microwaves

Advanced Functional Materials, 2019
Camouflage is an emerging application of metamaterials owing to their exotic electromagnetic radiative properties. Based on the use of a selective emitter and an absorber as the metamaterials, most reported articles have suggested the use of single‐band ...

ON THE MICROWAVE EXPOSURE

Acta Ophthalmologica, 1982
During the last decades the use of microwaves has been common in the industry, medicine, household and armed forces. According to the literature microwaves may especially cause lens opacities and other serious health disturbances. The authors of this paper examined 121 radar workers, but nothing was found which could be connected to microwaves.

A Microwave Polarimeter

Review of Scientific Instruments, 1949
A microwave polarimeter is described which enables the determination of rotation of the plane of polarization of microwaves in the 3.2-cm band. The transmitter-analyzer utilizes klystron tube 723 A/B. The microwaves are fed into a horn which acts as a polarizing agent.
