Abstract:
1. A measuring apparatus comprising: a space arrangement structure that includes space regions surrounded by conductors in a plane; an electromagnetic wave emitter that emits electromagnetic waves towards an object held by the space arrangement structure, wherein the electromagnetic waves emitted from the electromagnetic wave emitter towards the space arrangement structure are incident on the plane containing the space regions at an angle; an electromagnetic wave detector that detects the electromagnetic waves that have passed through the space arrangement structure; and an analyzer configured to measure characteristics of the object by comparing a position of a dip in a waveform of measured frequency characteristics of a transmittance of the space arrangement structure when the object is absent with a position of a dip in a waveform of measured frequency characteristics of a transmittance of the space arrangement structure when the object is present, wherein the space arrangement structure holding the object is placed between the electromagnetic wave emitter and the electromagnetic wave detector in such a manner that the plane containing the space regions is orthogonal to a straight line connecting together the electromagnetic wave emitter and the electromagnetic wave detector, and the electromagnetic waves emitted from the electromagnetic wave emitter are converged towards a single point on the straight line after the electromagnetic wave emitter and before the space arrangement structure and the object.
