The Research about Dipole Array's Microwave-absorbing Characteristics

Both the back and forward transient scattering mechanisms of dipole array with different loading forms have been investigated from time-domain and frequency-domain. Using 4x8 dipole array as an example, the data of scattering from the array under the incidence of Gaussian pulses are obtained by finite differential time-domain method. The influences of the incident angle on the waveforms and loading form are analyzed and conclusions are drawn. From these characteristics and conclusions, it is possible to find a method to reduce both the back and forward scattering field of the array structure.
