有关farfieldexact3d函数参数坐标的问题

      老师您好,请问farfieldexact3d( "mname", x, y, z, opt)中,z的值是相对于监视器“mname”的距离 还是说它是一个坐标的绝对值呢? 举个例子就是farfieldexact3d( "monitor", x, y, 2e-6, opt);其中monitor的z轴坐标是4e-6m,得到的结果是距离“monitor”2e-6m处(即z=6e-6m处)的结果还是z=2e-6m处的结果呢?

      应该是据监视器的位置上投射,监视器并不知道绝对坐标。比如,把结构上表面设置为绝对坐标零,监视器位于4e-6m,你用z=4e-6m再计算,结果不可能与监视器上的一样。个别例子中的反算位相补偿应该是有问题的。
