Abstract

PURPOSE:To absorb the magnetic resonance well even in a high frequency, by using many reactance elements as loads. CONSTITUTION:Input and output apertures 40 and 50 are provided in a junction electrode plate of junction part, which consists of an earth conductor plate 10, a ferrimagnetic substance plate 20 magnetized to a magnetic resonance field in a prescribed frequency by a magnetic field 200, and a junction electrode 30, on the line passing the center of this junction part, and n pairs of apertures 601, 701, 602, 702- are provided in directions at angles + or -theta1, + or -theta2-+ or -thetan when the direction of the aperture 50 is denoted as 0 deg., and an inductor 611, a capacitor 711, an inductor 612, a capacitor 712 are loaded for these respective pairs, and input and output apertures 40 and 50 are loaded with series inductances 41 and 51 and parallel capacitors 42 and 52 and are connected to input and output ports 43 and 53. An inductor Li and a capacitor Ci loaded for the aperture at an angle + or -thetai are set to satisfy equations omegaLi=Z0tanthetai and 1/omegaCi=-Z0tanitheta (omega is a negative frequcency).
