Special Issue Information

Dear Colleagues,

This Special Issue (SI) is entitled “Recent Advances in Micro/Millimeter-Wave Imaging Technology”. In the past 20 years, micro/millimeter-wave technology has achieved great progress, benefiting from the market demand for communications, public security, and medical diagnostics. The performance of vacuum microwave sources, solid-state microwave devices, and microwave integrated circuits has improved by several orders of magnitude. Those breakthroughs, on high-power source and super sensitive detectors, provide essential technologies for advanced microwave imaging realization. High-speed data acquisition and steaming are established for micro/millimeter-wave real-time visualization applications on the sensor industry, defense systems, fusion diagnostics, cancer diagnosis/prevention, agriculture, public security, galaxy telescope, etc. Artificial intelligence and image neural network learning technology are also high-priority topics in the development of imaging technology. Integrated circuit (IC) technology facilitates combing many bulky microwave components onto single, tiny pieces of the semiconductor substrate. Such a compact ‘system-on-a-chip’ (SoC) can be inexpensively customized for fully optimized instruments. Undeniably, SoC is becoming one of the most important development trends of micro/millimeter-wave imaging technology, which provides the ultimate solution for the high integration level, high performance, strong tolerance in the harsh environment, and superior compatibility of the micro/millimeter-wave imaging system. We look forward to the latest research on micro/millimeter-wave in terms of technologies, applications, and visualization algorithms. Authors are encouraged to submit contributions in any of the following or related areas for micro/millimeter-wave imaging:

  • Cutting-edge semiconductor technology application on microwave imaging;
  • Vacuum electronics device development;
  • Industry microwave sensor development;
  • Data acquisition and steaming instruments for microwave imaging systems;
  • High-frequency microwave transmitter/receiver module development;
  • Synthetic simulations for microwave imaging technology;
  • Image neural network learning development;
  • Micro/millimeter-wave telescope development;
  • Visualization diagnostics for medical applications;
  • Ultra-wide bandwidth microwave imaging applications; 
  • High frequency/speed microwave imaging applications; 
  • Integrated circuit development for microwave imaging.

Recently, studies on the remote detection of dangerous objects on the person have gained importance with increased security problems. Therefore, the use of passive millimeter waves in security systems is increasing because they are harmless to health and can penetrate clothes. In this study, a compact low-noise radiometric sensor (LNRS) that can be used to view hidden objects on the person was constructed. The LNRS can be arrayed thanks to its small size and ease of use, and can be used in imaging applications thanks to the 0.24 K resolution obtained. In addition, a passive millimeter imaging system (PMMWI) was developed to obtain images with the LNRS. The PMMWI system, which is realized in a quasi-optical structure, can be used in many experimental studies thanks to its compact structure. Full article
