Abstract
The paper describes a resistor whose active impedance grows with frequ ency due to the skin effect. Thin disks from a material with a high re sistivity and, possibly, with a high magnetic permeability are layered coaxially on a low-resistivity cylindrical conductor. Contact bushes are placed between adjacent disks on the cylinder surface. The device passes low-frequency current with small loss but significantly damps h igh-frequency current. At high frequencies the resistor absorbs a larg e amount of energy and can be heated to high temperatures.
