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

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.

SUMMARYSample preparation for microscopy is based on physical and chemical processes. These processes can be influenced by microwave irradiation. The prerequisite for the development of good microwave procedures is knowledge of histochemistry combined with understanding of the physics of microwave irradiation.

In this article, we provide a comprehensive review of past and present efforts in the field of microwave nonreciprocity with an emphasis on the most commonly used nonreciprocal devices, namely gyrators, isolators, and circulators. After discussing the origin and history of such efforts, we elaborate on the pros and cons of four distinct approaches to ...

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.

AS readers of these columns will be aware, workers in the Radiation Laboratory of the Massachusetts Institute of Technology are producing a series of books on microwave techniques which, when complete, will contain twenty-eight volumes, one of which is to be an index of the whole series.

This study has shown that representative fungi, viruses, and aerobic and anaerobic bacteria, including spore formers, can easily be killed in a conventional microwave oven with proper modifications. Metal instruments, including air turbine handpieces and burs, and acrylic dentures can be sterilized in short periods.
