Microwave heating of waste results in chemical breakdown that can lead to conversion mixed materials fuel. Heating mixtures with microwave energy rather than incineration faster and therefore be more efficient. Here we address small volumes food widely differing temperature-dependent electrical properties. Uniform is accomplished mode mixing within a loaded cavity by spatial power combining sol...

In this paper, we present new results in the development of a broad-band spatial power-combining system implemented in a standard X-band waveguide environment. Using 24 off-the-shelf GaAs monolithic-microwave integrated-circuit (MMIC) power amplifiers integrated with tapered-slot antenna arrays, the new combining circuit produced up to 126-W maximum power output with a gain variation of 1.9 dB ...

The long wavelength modes lost to bright foregrounds in the interferometric 21-cm surveys can partially be recovered using a forward modeling approach that exploits non-linear coupling between small and large scales induced by gravitational evolution. In this work, we build upon considering how adding external galaxy distribution data help fill these modes. We consider supplementing at two diff...
