Abstract: In at least one example of the present disclosure, a portable electronic device includes a housing, an internal volume within the housing, a port having a perimeter defined by the housing, the port in fluid communication with the internal volume and an external environment, a water deflector disposed inside the housing adjacent to the port, the water deflector extending at least a length and a width of the port, and openings disposed in the water deflector. The openings in the water deflector are aligned outside of the perimeter of the port.

Abstract: A radiofrequency (RF) source for use in testing radiofrequency interference (RFI) stresses has an RF transmitter emitting an electromagnetic field corresponding to at least one frequency, power, and state-of-polarization (SOP). Drives rotate the transmitter to emit, in a temporally continuous fashion, RF power and RF state of polarization from the RF transmitter in, respectively, every direction and every SOP orientation within an RF reflective structure in order to effectively characterize RFI stresses on said equipment to be tested.
