Abstract

The invention discloses a manual surface plasmon transmission line of a periodic loaded resistor and a method of adjusting dispersion and losses. A medium substrate and a resistance-loaded manual surface plasmon section on the medium substrate are included. The resistance-loaded manual surface plasmon section includes a metal graph and a chip resistor. The metal graph includes a metal strip and a plurality of metal sheets. The metal sheets are located on a same side with the metal strip. A slit is arranged between the metal strip and the metal sheets. One end of the chip resistor is welded with the metal strip, and the other end is welded with the metal sheets. Compared to the prior art, by using the transmission line of the invention, through loading the chip resistor in the manual surface plasmon transmission line, on one hand, large losses are possessed; on the other hand, through changing a resistance of the loaded resistor, the dispersion and the losses of the transmission line can be adjusted; simultaneously, the method of adjusting the dispersion and the losses are also provided; and the manual surface plasmon transmission line of the periodic loaded resistor can be used for constructing a load, an attenuator, an isolator, a switch and other loss devices and a circuit.
