Claim 3:
4. A contactless datalink configured to transmit data between a stationary part and a rotatable part and configured to rotate around an axis of rotation, the datalink comprising a ring-shaped dielectric waveguide,
wherein:
(a) the ring-shaped dielectric waveguide includes a first dielectric waveguide component at the rotatable part and a second dielectric waveguide component at the stationary part;
(b) the ring-shaped dielectric waveguide includes a center axis aligned with the axis of rotation;
(c) the ring-shaped dielectric waveguide includes a gap between the first dielectric waveguide component and the second dielectric waveguide component;
(d) the first dielectric waveguide component includes at least one rotatable waveguide section, the at least one t rotatable waveguide section having two rotatable waveguide section ends,
wherein one end of said two rotatable waveguide section ends is connected to at least one of a first transmitter, a first receiver, and a first absorber and the other end of said two rotatable waveguide section ends is connected to at least one of a second transmitter, a second receiver, and a second absorber;

(e) the second dielectric waveguide component includes at least one stationary waveguide section, the at least one stationary waveguide section having two stationary waveguide section ends,
wherein one end of said two stationary section ends is connected to at least one of a third transmitter, a third receiver, and a third absorber and the other end of said two stationary section ends is connected to at least one of a fourth transmitter, a fourth receiver, and a fourth absorber;

wherein one end of said at least one rotatable waveguide section is connected to a transmitter of the first and second transmitters and the other end of said at least one rotatable waveguide section is connected to a receiver of the first and second receivers; and
wherein one end of said stationary waveguide section is connected to a transmitter of the third and fourth transmitters, and the other end of said stationary waveguide section is connected to a receiver of the third and fourth receivers.
