A Möbius resistor is an electrical component made up of two conductive surfaces separated by a dielectric material, twisted 180° and connected to form a Möbius strip.
Its connectors are attached at the same point on the circumference but on opposite surfaces.
It provides a resistor with a reduced self-inductance, meaning that it can resist the flow of electricity in a more frequency-independent manner.
This means that a short circuit placed at this point doesn't influence the characteristics of the device.
Thus, the Möbius resistor can be thought of as two shorted lossy (resistive) transmission line segments, connected in parallel at the resistor's feed point.
