Isolation Circuit, System for Adjusting Characteristic of Isolation Circuit, Sheilding Device of Isolation Circuit and Method for Adjusting Characteristic of Isolation Circuit

摘要

The purpose is to adjust a characteristic of the isolation circuit with a simple control.;An isolation circuit 1 of the invention includes a cell region 20 including a plurality of arrayed cells 21, each of which has a first conductor 22 that has at least one capacitance CI, C2, a second conductor 23 that is connected to the first conductor 22, has an inductance, and is short-circuited to a common electric potential, and a feed line 24 that is placed without a connection with the first conductor 22 and the second conductor 23, each size of which is smaller than a wavelength X of a signal which is subject to operation of the cells 21; at least one power amount controller 25 that controls an amount of electric power to be fed to each of the feed lines 24 of the respective cells 21 of the cell region 20, thereby controlling either or both a dielectric constant and/or magnetic permeability of the cell region 20; and a circuit section 5 that is placed at a location where the circuit section undergoes action of either or both the dielectric constant and/or the magnetic permeability and that electrically isolates an input side from an output side.
