Abstract (in Japanese) (See Japanese page) 
(in English) A method and network for measuring complex electromagnetic (EM) fields is proposed. The method is based on a network of two input ports and four output ports, six-port network, where two voltage sources picked up by two EM probes are estimated in magnitude ratio and phase difference from powers measured at the output ports. When the network is arbitrary synthesized, estimated values are relatively sensitive to errors in measured powers. So adding some restrictions to the network property in a scattering matrix leads a newly proposed six-port network. The proposed network consists of quadrature hybrids.
To confirm whether the proposed network works well, we conducted some experiment. Those experimental results have good agreement with theoretical value.
