Microwave Blood Plasma Defroster
Journal of Microwave Power and Electromagnetic Energy, 1991A microwave blood plasma defroster capable of thawing up to four bags of frozen blood plasma at a time is described. The unit stops automatically when the plasma reaches a preset temperature, and all operating parameters are monitored for safety. Comparative testing showed that blood plasma thawed in this device was indistinguishable from plasma thawed

Cold atmospheric plasmas (CAP) may have the ability to improve cancer treatment, though the mechanisms of which are yet to be fully understood. Recent works have shown that Rayleigh microwave scattering (RMS) can be used to obtain the absolute value of the electron density in CAP. An RMS apparatus titled the Microwave Electron Density Device (MEDD) has

Simulating Plasma Microwave Diagnostics
Journal of Scientific Computing, 2006The paper presents computational simulations of plasma diagnostics via microwave absorption, where the number density of the charge particles and its collision frequency with the neutral particles are measured basing on the microwave attenuation phenomenon.

Pulse modulated microwave plasma etching
IEEE International Conference on Plasma Science, 1991Studies have been conducted on the etching characteristics of Si in a microwave plasma etching system having a pulse-modulated source. The experiments were performed at several pulse widths and duty cycles, as well as at cw, to determine how etch rate varied.

Transmission characteristics of a rectangular waveguide with a perpendicularly inserted mercury-vapor discharge tube, have been measured. The waveguide was excited in the TE01 mode and the plasma column was either perpendicular or parallel to the electric vector of the waveguide mode.

Microwave-Thawed Plasma for Cryoprecipitate Production
Vox Sanguinis, 1985Abstract. A microwave oven has been used to obtain rapid and controlled thawing of frozen plasma packs for cryoprecipitate production. The resulting factor VIII yields were higher than the average of 77.8 IU (in a volume of 17.2 ml) obtained by the slow overnight thaw procedures in routine use. Assays on 10 individual packs showed mean results of 142 ±

Microwave plasma assisted sputtering
Journal of Non-Crystalline Solids, 1997Abstract Indium tin oxide (ITO) films were prepared on SiO2 and on resin coated glass by microwave assisted sputtering and by magnetron dc sputtering using ITO targets. To find out the advantages of the microwave assisted sputtering in comparison to the magnetron sputtering the results of the two methods are compared. At substrate temperatures of 200°

Conductivity of Plasma to Microwaves
Physical Review, 1959Plasma conductivities for electrons with a Maxwellan energy distribution are evaluated for the cases in which the collision cross section is (i) velocity independent and (ii) inversely proportional to the velocity. The corresponding distribution functions of relaxation times are discussed. (auth)

Journal of the Institution of Electrical Engineers, 1963
Interest in the use of plasma devices as amplifiers and oscillators at microwave frequencies has been stimulated by the increased knowledge of plasma physics gained from thermonuclear research. Although of small value to the microwave engineer at present, these techniques may provide the means of attaining higher operating frequencies than those ...

IET Conference on High Power RF Technologies, 2009
A technique has been developed for melting holes in masonry as an alternative to conventional drilling. Microwaves are applied to a tungsten rod inside a section of waveguide, which is terminated by a short circuit. The rod protrudes from the waveguide, via a small hole, and is placed against the masonry to be drilled.
