“…Jiao et al proposed the application of 5.8 GHz magnetrons in asphalt pavement maintenance. By comparing the price, temperature rise, and heating depth of 2.45 GHz and 5.8 GHz magnetrons, it was found that the 5.8 GHz magnetrons can be effectively used for asphalt pavement maintenance [21,22]. Tang et al concluded that the microwave deicing efficiency is proportional to the microwave frequency and material dielectric loss using the CST (CST Studio Suite v2008 SP6, CST China Ltd., Shanghai, China), Matlab (Matlab2007b, MathWorks, Natick, MA, USA)., and ANSYS (ANSYS9.0, ANSYS, Pittsburgh, PA USA) simulation software.…”

A method of deicing using microwave heating is proposed to make scientific and economical road deicing in a cold area, and to make up for deficiencies in the existing methods for melting snow and ice. This paper proposes to define microwave deicing efficiency as the heating rate of a concrete surface when heated to 0 °C (the efficiency of deicing is equal to the difference divided by heating time, which is between 0 °C and the initial temperature at the junction of ice and concrete). Based on the mechanism of microwave heating and deicing, a method combining the finite element simulation model with indoor experiments was proposed to study the deicing efficiency of microwaves, and the effects of different microwave frequencies and different road structure materials on microwave deicing efficiency were analyzed. The results show that the microwave frequency and road structure materials have a great influence on microwave deicing. For asphalt concrete, the ice melting efficiency of 5.8 GHz is 4.31 times that of 2.45 GHz, but the heating depth is less than that of 2.45 GHz. At 2.45 GHz, the melting efficiency of cement concrete is 3.89 times that of asphalt concrete. At 5.8 GHz, the melting efficiency of cement concrete is 5.23 times that of asphalt concrete. Through the consistency of the simulation and experimental results, the validity of the simulation model based on the finite element theory is verified. The results provide theoretical guidance and a practical basis for future applications of microwave deicing.

Abstract-This paper describes the investigation of broadband interaction and harmonic suppression. A special dispersion shape used in broadband traveling-wave tubes (TWT) is obtained. The theoretical and simulation studies of negative dispersion are presented. On the basis of these studies, a broadband TWT used in microwave power module (MPM) is designed. Compared with the old TWT with flat dispersion, the new one with negative dispersion decreases the second harmonic content about 10 dB and improves the fundamental efficiency with a maximum increase of about 5% at the lowest frequency 2 GHz. The new one operates with the beam voltage of 3600 V and current of 250 mA. The modified TWT is fabricated and the simulation results meet the measurements very well.
