Abstract: Electromagnetic bandgap isolation systems and methods are provided. In one example, an electromagnetic bandgap isolator device includes a base support having a curved surface. The electromagnetic bandgap isolator device further includes a metamaterial. The metamaterial includes a continuous curved layer in contact with the base support. The metamaterial is configured to absorb energy associated with a frequency range. Related systems and methods are also provided.

Abstract: Techniques are disclosed for conjoint beam shaping for optimizing radar and sonar performance. A method may include determining a system pattern of an antenna system based at least on a first antenna pattern and a second antenna pattern. The first antenna pattern may be based on first antenna parameters. The second antenna pattern may be based on second antenna parameters. The method may further include determining a score based at least on the determined system pattern and reference information. The method may further include adjusting the first antenna parameters and second antenna parameters based at least on the score. Related systems and devices are also disclosed.

Abstract: There is described a method of operating a multi-mode communication unit. For each radio frame of a radio communication frame structure, the unit selectively sets a mode of radio frequency operation for one of transmission and reception for a selected radio frame duration, for operation in a radio communication mode of operation or in a sensing mode of operation. The unit may also interrupt a transmission task within a given radio frame at a time selected in accordance with a sensing instant of a second communication unit to which the data being transmitted and perform a different task for a duration of the sensing instant of the second communication unit.
