<p><P>PROBLEM TO BE SOLVED: To provide a compact thermoelastic actuator for a waveguide, a waveguide with phase stability, and a multiplexing device including such an actuator. <P>SOLUTION: The compact thermoelastic actuator (15) includes at least two identical stress components (10a, 10b, 10c, 10d) and a securing component (11), the securing component having a coefficient of thermal expansion smaller than the coefficient of thermal expansion of the stress components. The stress components (10a, 10b, 10c, 10d) are mounted to be arranged adjacently to one another head-to-tail parallel to a longitudinal axis Y, and are linearly offset relative to one another, along the longitudinal axis Y. The securing component (11) has two ends respectively linked to external ends of the respective stress components, and internal ends of the respective stress components are positioned under a median region (14) of the securing component (11). The actuator is applicable to a waveguide of a multiplexer incorporated in a space apparatus for an artificial satellite. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
