Abstract: Example embodiments relate to slanted radomes for protecting radar units. An example radar system may include a radar unit that includes at least one antenna having a radiation pattern. The radar unit is configured to transmit a radar signal based on the radiation pattern and receive radar signals. In addition, the radar system further includes a radome located in a direction of transmission of the radiation pattern. Particularly, the radome is aligned at an angle relative to a plane of the at least one antenna such that reflections of the transmitted radar signal caused by the radome are directed towards at least one of a null of the radiation pattern and an absorption component.

Abstract: A device is provided that includes a first waveguide configured to guide propagation of RF waves inside the first waveguide. A first side of the first waveguide is configured to emit an evanescent field associated with the propagation of the RF waves inside the first waveguide. The device also includes a second waveguide having a second side positioned within a predetermined distance to the first side of the first waveguide. The second waveguide is configured to guide propagation, inside the second waveguide, of induced RF waves associated with the evanescent field from the first waveguide. The device also includes a first probe coupled to the first waveguide and configured to emit the RF waves for propagation inside the first waveguide. The device also includes a second probe coupled to the second waveguide and configured to receive induced RF waves propagating inside the second waveguide.
