Heating mechanisms in radio frequency driven ultracold plasmas [PDF]
, 2012 Several mechanisms by which an external electromagnetic field influences the temperature of a plasma are studied analytically and specialized to the system of an ultracold plasma (UCP) driven by a uniform radio frequency (RF) field.

Deep-heating characteristics of an RF capacitive heating device
International Journal of Hyperthermia, 1985 An RF capacitive heating device was constructed and its deep-heating characteristics were studied using three mini-pigs. The deep-heating ability of RF capacitive heating was found to be improved by enlarging the electrodes, driving at 8 MHz, cooling the skin under the electrodes, inserting a bolus between the body and the electrodes and considering ...

Selective tumor heating by shortwave radiofrequency (RF) [PDF]
Cancer, 1980 Experimental solid tumors were treated in vivo with external high frequency dielectric heating to observe any heat selectivity between the tumor mass on one hand, and the subcutaneous tissue, muscle, and systemic temperatures on the other. Methylcholantrene-induced sarcoma cells were inoculated into the subcutaneous tissue or muscles of the posterior ...

RF HEATING EXPERIMENTS IN THE WEGA TOKAMAK
Le Journal de Physique Colloques, 1977 To the WEGA Tokamak plasma, up to 90 kW RF power near the lower hybrid frequency (500 MHz) have been applied using interna1 coupling structures. Measurements of electron temperature profiles by different methods are presented. It appears that the electrons do not absorb a significant fraction of HF power. Fast ions are produced during the HF which flux

Effects of radio-frequency fields on bacterial cell membranes and nematode temperature-sensitive mutants [PDF]
, 2006 Membrane-related bioeffects have been reported in response to both radio-frequency (RF) and extremely low-frequency (ELF) electromagnetic fields (EMFs), particularly in neural cells.
