field frequency

field frequency

[′fēld ‚frē·kwən·sē]
(electronics)
The number of fields transmitted per second in television; equal to the frame frequency multiplied by the number of fields that make up one frame. Also known as field repetition rate.

"Thus, irradiation with an electromagnetic field frequency of 918 MHz can probably be used in the treatment of Alzheimer's disease patients."
When the relaxation time increases, the viscous stretch becomes smaller, that is, because the viscoelastic deformation of the DE fails to keep up with electric field frequency leading to decreasing the viscous stretch.
To excite the SW, a sinusoidal magnetic field H = [H.sub.0] sin (2 [pi]ft) is applied along the y-axis at x < 50 nm, where f and [H.sub.0] are the field frequency and amplitude, respectively.
Microwave frequency 9.3-9.4 GHz Intensity of microwave 12 mW Range of maneuvering magnetic field 20 mT Modulated magnetic field frequency 100 kHz Modulated magnetic field amplitude 1.0mT Sampling time 81.92 ms Accumulation count 3 times Measurement temperature 10 K (liquid He cooling) Standard substance 1-Diphenyl-2-picrylhydrazyl (DPPH) Index Mn marker ([Mn.sup.2+])
1b) depend on AC field frequency. The time of their formation also depends on frequency.
Dependence of the maximum temperature of the sample, [T.sub.max], on the applied field frequency is presented in Figure 4.
In the case of structure number 1 (see Figure 4) that has the less value of r, for the AC field frequency h[omega] = 4[GAMMA] it results that, at high values of the Fermi energy [[epsilon].sub.F] = 0.1 eV (corresponds to the contacts' donor density [n.sub.d] = 1.3 x [10.sup.18] [cm.sup.-3]), the operating point is located to the left of the maximum NDC area (i.e., at a lower DC voltage).
Let's determine the dependence of the shielding factors on the external field frequency for a circular passive loop and conductive shells (spherical and cubic) placed in the homogeneous low-frequency MF.
All the experiments were performed at a field frequency of 50 Hz sinusoidal at intermittent exposure.
Thereby, the dependence of the Clausius-Mosotti factor on the electric field frequency allows for a wide range variation of the force acting on a cell.
As interfacial polarization takes place at large scale (mesoscopic scale), it has usually been observed at low frequencies, due to its large relaxation time with respect to electric field frequency at high frequencies.
Time field frequency features that are used include mean, domain, maximum and vibration signal Kurtosis coefficient.
