The microwave-slot coupling into a rectangular cavity with an interior structure is investigated theoretically and numerically. With complementary antenna theory, the paper deduced the resonant enhancement factor of narrow slot and simulated the coupling structure using the finite-difference time-domain (FDTD) algorithm. The simulation results reveal that the resonant and enhancement effects existing...
The coupling of Ultra Wideband (UWB) pulse entering cylindrical cavity connecting slot is simulated and analysed employing finite differential time domain (FDTD) method. Through time and frequency domain analysis, electric field coupling for different UWB pulse widths, resonant and enhancement effects of cylindrical cavity are investigated and the coupling characteristics of electric field and cavity...
In this paper, we studied linear coupling function of the ultra-wide-band (UWB) pulse coupled to the computer case with different kinds of slots, apertures and hole arrays by the finite-difference time-domain (FDTD) method combined with fast Fourier transform (FFT) method.
In this paper, the lightning-generated electromagnetic fields over lossy ground produced by lightning strikes either to flat ground or to a tall tower are calculated using the 2-D finite-difference time-domain (FDTD) method. The resultant horizontal and vertical electric fields are used as forcing functions in the discretized Agrawal electromagnetic coupling equations for the calculation of induced...
