Abstract
The method proposed for calculation a coil in free space is presented. Eddy current transducer mathematical model as a spiral flat inductor in free space is designed as example. It allowed to calculate its impedance, considering skin effect in conductor and to estimate its quality. The model is obtained with assump-tions about current distribution in a conductor using the discrete Hankel transform that re-duces machine time significantly. Current distribution function is based on phenomena re-versibility in nature, namely, electromagnetic field creates definite current distribution in conductive medium and such current distribution in conductive medium creates the same electromagnetic field in free space. Flat inductor impedance and coil quality at 1 MHz and DC are calculated.

Tunnel Diode Macro-model in the Electronic Circuits Modeling Systems
Introduction. The circuit simulation programs that are currently in use do not have tunnel diodes macro-models in their standard libraries. So it is important to create and examine a circuit diagram of tunnel diode macro...
Two-stage causal unifrom image filtration with presence of correlated noise
Introduction. Quality of raw single SAR images is low due to the presence of a specific type of noise in the form of speckle noise. Therefore it is necessary to use filtering for SAR images preprocessing. However, the de...
