The phenomenon of cell electroporation due to low-intensrty transient electromagnetic pulses was studied by using a broad band transverse EM-wave cell (BTEM CELL).
The aim of our current work is to construct an algorithm for solving problems of radiation and detection of transient electromagnetic waves in the analysis of permeable bodies.
Based on the known algorithms in DC resistivity on wave-number distribution and selection, we proposed a principle on how to choose the least wave-number concerning the central-loop transient electromagnetic method.
The algorithms, programs, as well as the results are discussed for the recovery of electromagnetic and geometric parameters of casing string by borehole measurements of electromotive force with the help of the transient electromagnetic method.
D transient electromagnetic field for a layered model has been computed numerically by using the G-S inverse Laplace transform, and a new Random search method is used to complete the TEM inversion. The results show that this inversion technique is stable and independent on the first model.
n this paper,thebehavious and character of time partial derivative of vertical magneticfield and its apparent resistivity for the TEM late time field excited by vertical magnetic dipoleand horizontal electric dipole are discussed.Some problems about one dimensional inversion forthem are studied,a practically applied inverse program is designed.It is shown that this in-verse program has better applied effect.
In view of the fact that the calculation precision Of the late stag6 field of the transient sounding ig commonly rather low, the present paper, on the basis of the odd-even character of the real and imaginary components of the frequerey domain electronagnetic field and the derivative character of the Fourler transform and using cosine transform, has realized the conversion of the electromagnetic field from the frequency domain to the time domain. It is shownthat the calculation of late-stage transient elec...
