The Tip part of the inner conductor and the external conductor of three dimensional electric field measurement mannered

摘要

PROBLEM TO BE SOLVED: To measure a three-dimensional electric field by only rotational operation of a probe.;SOLUTION: The edge parts of an inside conductor and an outside conductor of a coaxial cable are arranged to be exposed from an edge face inclined to a center axis. An engagement member rotating these edge parts is provided, and an electric field detection probe can be rotated. The electric field detection probe can measure an orthogonal three-axis electric field by detecting the electric field of positions rotating the axis up to 90 and 180 degrees by only insertion from one direction to an object to be measured. In addition, a minute region electric field can be measured by thinning down the diameter of the probe. The rotational operation of the probe disturbs a region to be measured, and eliminates a case having a breaking possibility.;COPYRIGHT: (C)2004,JPO&NCIPI
