Embodiments of the invention include dielectric waveguides and connectors for dielectric waveguides. In an embodiment a dielectric waveguide connector may include an outer ring and one or more posts extending from the outer ring towards the center of the outer ring. In some embodiments, a first dielectric waveguide secured within the dielectric ring by the one or more posts. In another embodiment, an enclosure surrounding electronic components may include an enclosure wall having an interior surface and an exterior surface and a dielectric waveguide embedded within the enclosure wall.

A cooling system comprises a heat sink that bears on an electronic component (120) on a printed circuit board, and a cooling channel for a coolant. The cooling channel has a cavity for the heat sink, and the heat sink is designed to be placed in the cavity based on a distance between the component and the printed circuit board such that the printed circuit board can be placed on the cooling channel at a predetermined spacing thereto, such that the component bears on the heat sink.

Phased array antennas, such as a multi-function aperture, are limited in performance and reliability by traditional air-cooled thermal management systems. A fuel-cooled multi-function aperture passes engine fuel through channels within the ribs of the multi-function aperture to provide better heat transfer than can be achieved through air cooled systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.
