Differential Heating of Metal Nanostructures at Radio Frequencies

Physical Review Applied, 2021
Nanoparticles with strong absorption of incident radio frequency (RF) or microwave irradiation are desirable for remote hyperthermia treatments. While controversy has surrounded the absorption properties of spherical metallic nanoparticles, other geometries such as prolate and oblate spheroids have not received sufficient attention for application in ...

Influence of Radio Frequency Heating on Sperm

Nature, 1963
THE influence of temperature on the survival of spermatozoa in vitro1 and the influence of high temperatures on the reproductive capacity of guinea pigs' spermatozoa have been investigated2 by many workers.

The Radio Frequency Heating of Magnum-psi

Fusion Science and Technology, 2005
Magnum-psi is a linear device to be constructed at the FOM-Rijnhuizen institute and designed to produce plasmas allowing the study of plasma-surface interaction processes relevant to the ITER divertor. The plasma cross-section will be about 100 cm{sup 2}, the plasma density around 10{sup 20} m{sup -3} and the temperature around 3eV.

Frequency-Selective Heating at Radio Frequencies

Nature, 1950
THE differential heating of the components of a heterogeneous mixture by radio-frequency fields is a well-known fact1,2, and the variation of the effect with frequency is often regarded as an important principle in various applications of radio- and micro-waves, for example, short-wave therapy and radio-heating.

Heating of radio-frequency cables

Electrical Engineering, 1949
IN CONSIDERING the heating of radio-frequency cables due to internal causes, there first must be determined the distribution and intensity of the generation of heat caused by the conductor and dielectric losses. Then the diffusion of the heat throughout the cable and its dissipation at the surface are considered in order to determine the resulting ...

Heating mechanisms in gold nanoparticles at radio frequencies

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
Gold nanoparticles are under study as a potentially viable mechanism for hyperthermia tumor treatment in two regimes of the electromagnetic spectrum: laser and radio frequency excitation. Gold nanoparticles, nanorods and nanoshells have been applied with visible laser sources that excite the particles at or near their plasmon resonance frequency, and ...

Radio-frequency heating of a plasma

Canadian Journal of Physics, 1970
If a uniform plasma is surrounded by a heating coil in the presence of a steady axial magnetic field, it is shown that a considerable increase in power absorption may be expected if the operating frequency is chosen to be close to a magneto-acoustic resonance of the plasma column. This effect is due to a very large increase in the oscillating field at

Principles of Radio‐frequency Heating

Journal of the Society of Dyers and Colourists, 1982
The conservation of energy or the introduction of new techniques which will allow less energy to be used is an important area of activity for the Scarce Resources Committee. Accordingly, very successful half‐day symposia were held in 1980 to discuss the application of radio‐frequency techniques in textile processing.

Economic aspects of radio-frequency heating

Electrical Engineering, 1948
The importance of industrial applications of radio-frequency heating is emphasized by the growth of this field which has expanded into a business with an eight million dollar annual volume. Thus, an economic analysis of some of the problems including cost data in specific industries is of interest.
