Abstract

The statistics of the fields within an enclosure illuminated by an external field via an aperture have been investigated using Monte-Carlo methods. The field statistics in the volume of the enclosure are shown to correspond to the Rayleigh statistics found in properly functioning reverberation chambers when a sufficiently large number of modes is excited. The variation of field behaviour near the conducting walls is investigated. The deviation of the field statistics from the Rayleigh distribution as the number of excited modes falls is also investigated.

具有孔径效应的壳体的场统计——q因子和模数的影响
本文用蒙特卡罗方法研究了外场经孔径照射的封闭体内场的统计。当有足够多的模态被激发时,在正常工作的混响室中,显示出在封闭体积内的场统计量与瑞利统计量相对应。研究了导体壁附近电场行为的变化。研究了随激振模数的减少,场统计量与瑞利分布的偏差。
