Claim:
1. A gyrator for AC signals, comprising: a Hall effect material, means for permeating this Hall effect material with a magnetic field that is perpendicular to the plane or surface of the material, at least one input port for coupling an alternating current (I at least one output port for outcoupling an output voltage (U wherein each port comprises at least two terminals that are connected to the outside, wherein at least one terminal of each port is connected to a connecting electrode, which is electrically insulated from the Hall effect material and forms a capacitor together with the Hall effect material, and wherein along an outer edge of the Hall effect material leading from said one terminal to said connecting terminal the Hall effect material has a local capacitance per unit length less than a prescribed value selected to meet a boundary condition for avoiding local magnetoplasmon resonance while allowing a continuous potential progression in a region of the Hall effect material located directly opposite an edge of the connecting electrode of said capacitor, and wherein the local capacitance per unit of length measured along said outer edge of the Hall effect material, which leads from the connecting electrode connected to the input port to the connecting electrode connected to the output port, is lower in the edge regions of the connecting electrodes than in the remaining regions of the connecting electrodes.
