This general class of application is one of many methods that are sometimes called “nondestructive evaluation” (NDE). In order to examine the impact of a high-frequency magnetic field in forming eddy currents, it is convenient to use the example of a thin cylindrical sheet, as shown in ...
For PICMI, the cfl number for electrostatic simulations is now controlled by the warpx_cfl parameter in the ElectrostaticSolver class. Users may also specify a warpx.max_dt and warpx.dt_update_interval. The former parameter specifies the maximum allowable timestep and additionally sets the initi...
The result is extended to a special class of capacitors in which the electrodes are the equipotential surfaces generated by the equilibrium charge on the object. This extension allows analytical expressions of capacitance for confocal spheroidal capacitors and finite cylinders. Moreover, a second order...

Most of the electrical power in this country has a frequency of 60 cycles per second, although some 25-cycle power is still in use in various localities. The secondary voltage, Es, may be found by applying this simple formula: Suppose we have a transformer whose primary has 500 turn...
We give a simple and systematic derivation of the RF energy formula, Eq.11, using Eq.7. For this purpose, we reinterpret the “cavity” using the notion of the charge neutralization, which turns out to be an idea that is really in harmony with this. ...

The thickness of the shell layer can be presumed, for example, based on the specific surface area of the toner core, the amount of the monomer of the thermosetting resin and the amount of the thermoplastic resin in accordance with the following formula: Thickness of shell layer=(amount of ...
