Electrical conductivity of tissue at frequencies below 1 MHz.
A two-pronged approach, review and measurement, has been adopted to characterize the conductivity of tissues at frequencies below 1 MHz. The review covers data published in the last decade and earlier data not included in recent reviews. The measurements were carried out on pig tissue, in vivo, and pig body fluids in vitro. Conductivity data have been obtained for skeletal and myocardial muscle...
متن کاملA calibration system for electric power at frequencies up to 1 MHz
Electrical power measurements are a central part of society today. Traditional power measurements have been focused on the power delivered by the 50 Hz or 60 Hz electrical grid with up to about 50 harmonics. This means that the bandwidth of such a power meter only needs to be a few kHz. Most modern electrical devices and machines are powered by batteries, or by the grid via DC converters. Ironi...
متن کاملComputational Dosimetry on Contact Currents from Charged Human Body
Contact current, defined as indirect effects of electromagnetic fields, flows a human body when contacting with an object such as a metal structure at a different electric potential, and may stimulate muscle and peripheral nerve. Thus, numerical analyses of electric fields induced by contact currents in a human body have been performed. Computational methods and evaluations of effects of transi...
متن کاملCCE 92-05 intercomparison of ac-dc voltage transfer standards at high frequencies (1-50 MHz)
From August 1995 to May 1998, the CCE 92-05 intercomparison of ac–dc voltage transfer standards at high frequencies was carried out. Two travel standards were measured by 15 national standards institutes. The results in the frequency range from 1 to 50 MHz show a good agreement between the majority of participants. The span of the majority of the reported ac–dc differences at 50 MHz is less tha...
متن کاملComplex permeability of soft magnetic ferrite/polyester resin composites at frequencies above 1 MHz
Composite soft magnetic materials consist of magnetic particles in a non-magnetic matrix. The properties of such materials can be modelled using effective medium theory. Measurements have been made of the complex permeability of composites produced using ferrite powder and polyester resin. The success of various effective medium expressions in predicting the variation of complex permeability wi...
