Abstract (en)
An electromagnetic wave attenuation control device for use in a communication link comprises an absorbent body (33) which is controllably inserted into a section of waveguide (34) by an actuator (24). The actuator is controlled in response to characteristics such as changes in the power level of the electromagnetic energy transmitted by the waveguide or changes in the uplink power requirements of the communications link or both. <IMAGE>
