Patent number: 6882144Abstract: An electromagnetic wave measuring apparatus includes a loop probe section having loop probes whose loop planes are placed so as to be perpendicular to each other, and each loop probe is placed so that its magnetic field detection space is not interfered with by other loop probes. If the loop probe section is placed at measurement position coordinates xi, yj, it detects a magnetic field component at the measurement position coordinates xi, yj, which is parallel to an XY plane, and a magnetic field component in a Z-axis direction at measurement position coordinates xi, yj?1, and repeats measurement by pitch p in a positive Y-axis direction. By calculating the root sum square of the detection results at each measurement position coordinate, a three-dimensional magnetic field level of an object to be measured can be obtained at each measurement position coordinate as electromagnetic field distribution with high-precision.Type: GrantFiled: February 27, 2004Date of Patent: April 19, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shoichi Kajiwara, Akihiro Ozaki, Koichi Ogawa, Yoshio Koyanagi, Yoshitaka Asayama, Yutaka Saito
