Radio Frequency Heating for Soil Remediation

Journal of the Air & Waste Management Association, 1999
Radio frequency heating (RFH) is a technology that increases the cost-effectiveness of a variety of site remediation technologies by accelerating the rate of contaminant removal. Heating makes the physical, chemical, and biological properties of materials such as contaminants, soil, and groundwater more amenable to remediation.

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 ...

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 ...
