APPARATUS INCLUDING OBJECT AND SENSOR AND METHOD HAVING STEP OF EXCITING THE OBJECT AND A STEP OF DETECTING FIELD INTENSITY

摘要

PROBLEM TO BE SOLVED: To provide an improved antenna and microwave transceiver. SOLUTION: An apparatus includes an object and one or more sensors located adjacent to or in the object. The object is formed of a material whose dielectric constant or magnetic permeability has a negative real part at microwave frequencies. The one or more sensors are located adjacent to or in the object and measure an intensity of an electric or a magnetic field therein.
