Abstract: An electromagnetic wave guidance and beam reshaping structure is favorable to incorporate a radiation source antenna into an energy focusing system. The electromagnetic wave guidance and beam reshaping structure includes a substrate, a plurality of metal patterns and a plurality of hollow structures. The substrate includes a central portion and a peripheral portion that surrounds the central portion. The plurality of metal patterns are disposed on the central portion. The plurality of hollow structures are disposed in the peripheral portion. The metal patterns are axisymmetrically arranged with respect to a central axis of the substrate, and the hollow structures are axisymmetrically arranged with respect to the central axis of the substrate.

Abstract: A frequency reconfigurable phased array system comprises a signal generator outputting a power signal with an adjustable frequency, a plurality of radio frequency (RF) modules receiving the power signal, a control module generating excitation mode parameter sets and material processing event sets, a first database storing the excitation mode parameter sets, and a second database storing the material processing event sets. The control module generates a material processing schedule by selecting one of the material processing event sets based on a material recipe, an average power, and a total time of a material, and controls a signal frequency of the signal generator according to the material processing schedule and the excitation mode parameter sets, and a RF phase and a RF power of each of the RF modules, to have the RF modules generating a power signal.
