Abstract (en)

The electrodynamical rigorous solutionof Maxwell's equations related to the microwave pulse propagation inside a three-dimension heart model is presented here. The boundary problem was solved by using the singular integral equations' method. The carrier microwave frequency is 2 GHz. The modulating signals are triangular video pulses with the on-off time ratio equal to 5 and 100. The model heart was limited by a non-coordinate shape surface and it consisted of two different size cavities. The heart cavities were schematic images of the left and right atriums and ventricles. In our calculations the cavities were filled with blood with the permittivity ε2=60-i19 and the walls of the heart consisted of myocardium tissue with the permittivity ε1=55-i17. Microwave electric field distributions were analysed at three longitudinal cross-seetions of the heart model.
