Radio frequency communication
A differential transmission transition interface is disclosed which can include first and a second buried conducting tracks providing respectively first and second differential couplings between a differential rf transmission output and a waveguide; the first buried conducting track extending over an opening of the waveguide to provide a first rf coupling element; and the second buried conducting track extending over the opening to provide a second rf coupling element. At least a portion of the first rf coupling element extends over the waveguide opening in a first angular direction; and at least a portion of the second rf coupling element extends over the waveguide opening in a second angular direction that is opposed to the first angular direction..

Ultrasonic actuator for a linear ultrasonic motor and linear ultrasonic motor having an ultrasonic actuator
Wherein the at least one primary waveguide resonator (2) and the at least one auxiliary waveguide resonator (4) is/are designed as an open linear waveguide, and the at least one crosspiece (6) functions as a totalising device of the acoustic standing waves propagated in the primary and auxiliary waveguide resonators (2, 4), so that the at least one crosspiece (6) functions as the generator of a simulated travelling wave, which is usable for driving the positioning element (7).. .
