【摘要】 本文从混响室双模电磁场结构的假定出发,理论上证明了一维条件下采用对称模和反对称模发射能有效改善混响室内电磁场的均匀性,并指出反对称模发射可以最大程度改善双模电磁场的整体均匀性,并绘出单一发射、对称模发射和反对称模发射等不同条件下混响室内电磁场比较图更多还原

【Abstract】 The electromagnetic field states in reverberating chamber can be marked off five parts. Based on 1 dimension double-mode EM field supposition, this paper proved theoretically that it can improve effectively the electromagnetic field uniformity in reverberating chamber by symmetric and anti-symmetric mode emission and the later can improve farthest the integral uniformity of double modes electromagnetic field. Finally, some EM field simulate chart is given.更多还原
