In the paper, a new type of high-frequency microwave heating method for windshield forming process was investigated. In order to obtain the effects of forming process parameters and windshield properties on the forming qualities of windshield, the distributions of electromagnetic energy and temperature were simulated by coupling electromagnetic analysis with multi-physics analysis. Moreover, the influence of different microwave input frequencies on electromagnetic energy and temperature distributions was analyzed. The results show that a travelling-standing wave distribution of electromagnetic energy is formed within windshield. And the temperature distribution and heating time are determined by combined influences of windshield properties and microwave frequency. And the necessary temperature distribution can be realized by electing appropriate microwave frequency.

High Frequency Microwave

With the development trend of wireless and broadband in the communication link and even the whole information industry, the demand of high-frequency microwave bandwidth has been increasing. The RoF network system solves the problem of spectrum congestion in low-frequency band by providing an effective technology for the distribution of high-frequency microwave signals over optical fiber links. However, the traditional mm-wave generation technique is limited by the bandwidth of electronic devices. It is difficult to generate high-frequency and low-phase noise mm-wave signals with pure electrical components. The mm-wave communication technology based on photon assisted can overcome the bandwidth bottleneck of electronic devices and provide the potential for developing the low-cost infrastructure demand of broadband mobile services. This paper will briefly explain the characteristics of the RoF network system and the advantages of high-frequency mm-wave. Then we, respectively, introduce the modulation schemes of RoF mm-wave generation based on photon assisted including directly modulated laser (DML), external modulation, and optical heterodyne. The review mainly focuses on a variety of different mm-wave generation technologies including multifrequency vector mm-wave. Furthermore, we list several approaches to realize the large capacity data transmission techniques and describe the digital signal processing (DSP) algorithm flow in the receiver. In the end, we summarize the RoF network system and look forward to the future.
