Abstract: The present disclosure relates to systems and methods for using microwave energy in various additive manufacturing (“AM”) processes to make a part. In one embodiment a system is disclosed having an electronic controller, a microwave energy generator subsystem responsive to the electronic controller for generating a microwave energy signal, and a beam patterning component for patterning the microwave energy signal into a microwave beam having a desired spatial energy distribution profile for at least one of curing or sintering a feedstock material being used to form a part. The beam pattering component in one implementation is movable relative to the feedstock material, and within an X axis and Y axis plane.

Abstract: Multistatic radar systems and associated methods are disclosed herein. In some embodiments, a multistatic radar system can include multiple radar transmitters and multiple radar receivers. The transmitters are configured to generate radio-frequency (RF) signals in a target volume, and the receivers are configured to receive the RF signals after the RF signals are reflected off an object moving through the target volume. The transmitters and the receivers can be spaced apart and aperiodically positioned about the target volume. The receivers can sample and digitize the reflected RF signals at an RF frequency. The radar system further includes a processing device configured to determine a property of the object based on the sampled reflected RF signals.
