Abstract: A wireless communication system includes a transmitter configured to transmit at least first and second radio waves having respective different frequencies F1 and F2, an electrically conductive first passive substantially linear medium, an electrically conductive first passive substantially nonlinear medium disposed proximate the first passive substantially linear medium, and a first magnetic film covering at least a portion of the first passive substantially linear medium. When the transmitter transmits the first and second radio waves, the first passive substantially linear and nonlinear media receive the first and second radio waves and generate first and second signals propagating therein at the respective frequencies F1 and F2. At least one intermodulation signal having a frequency F3 equal to nF1+mF2, where m and n positive or negative integers, is generated in the first passive substantially nonlinear medium. The first magnetic film reduces the at least one intermodulation signal by at least 2 dB.

A spatial power-combining device includes a plurality of amplifier assemblies, and each amplifier assembly includes an input antenna structure, an amplifier, and an output antenna structure. At least one of the input antenna structure and the output antenna structure may have a profile that includes tuning features, such as steps or other shapes, configured to tune or match with a desired operating frequency range. The tuning features may be configured with one or both of a signal conductor and a ground conductor of at least one of the input and output antenna structures. The tuning features may be non-symmetric across a particular signal conductor or a ground conductor, and the tuning features of a signal conductor may be non-symmetric with the tuning features of a ground conductor.

Abstract: The present disclosure relates to a shock absorbing arrangement suitable e.g. for ship installed structures comprising a rod, a resilient member arranged in connection to the rod, a structure element and a locking member arranged in connection to the structure element. The locking member is arranged to detachably lock the structure element at a resting position at the rod and the locking member, or the structure element, is supported by the resilient member. The resilient member is configured such that a spring force of the resilient member acts to maintain the structure element essentially at the resting position at the rod. The locking member is further configured to release the structure element from the resting position when being exposed to a force exceeding a predetermined holding force, whereupon the resilient member acts to reinstate the locking of the structure element at the resting position at the rod. The present disclosure further relates to a shock absorbing structure comprising such shock absorbing arrangements.
