Claim 9:
10. A method of electromagnetic signal transmission using a rotary joint, comprising:
coupling an electromagnetic signal from a first distal end of a first waveguide section of the rotary joint to a first proximal end of the first waveguide section;
coupling the electromagnetic signal from the first proximal end of the first waveguide section to a cavity of a shaft of the rotary joint, wherein the cavity is defined by an inner surface of the shaft and extends from a first end of the shaft to a second end of the shaft, wherein the first proximal end of the first waveguide section is positioned within the cavity of the shaft and secured to the inner surface of the shaft; and
coupling the electromagnetic signal from the cavity of the shaft to a second proximal end of a second waveguide section of the rotary joint, wherein the second proximal end of the second waveguide section is positioned within the cavity of the shaft and unsecured to the inner surface of the shaft to form a radial gap between an outer surface of the second proximal end and a laterally adjacent portion of the inner surface of the shaft, wherein at least a portion of the cavity of the shaft defines an inner surface of the rotary joint, and wherein the shaft and the first waveguide section are configured to rotate about a rotational axis and relative to the second waveguide section.
