Measurement of High-Power Microwave Impulse Response Characteristics of Reflector Materials

International Journal of Antennas and Propagation
High-power microwave (HPM) antenna, one of the key subsystems in the HPM system, is used for HPM radiation. Its performance is partly determined by the impulse responses of reflector materials under HPM.

Effect of Dissolved Oxygen on Aluminum Corrosion in Simulated Cooling Water for HVDC Systems at 50 °C

International Journal of Electrochemical Science, 2021
The corrosion behavior of aluminum in 50 °C deionized water with varying dissolved oxygen contents was studied. Compared with deionized water, an aqueous solution with dissolved oxygen promoted aluminum corrosion. With increasing dissolved oxygen content,
