With the advantages of non-ionisation nature and relatively low cost and complexity, microwave is widely used in many engineering fields, such as target recognition, target location, tumor detection and therapy, wireless power transfer, regional confidential communication, structural health monitoring, etc. While some technical bottlenecks need to be addressed, including resolution and accuracy of recovering target, especially in complex media and in the environment where target’s material is similar to the background material; the efficiency of long-distance wireless power transfer; the enhancement of quality of communication; the shaping and control of microwave field; the generation of arbitrary microwave field in a given limited region; the design of waveform and array for the aforementioned areas. This special issue aims to gather the latest, state-of-the-art progress in the research of microwave technology, and find the solution to address the aforementioned problems. Potential topics include, but not limited to:

1. Antenna and array: design and application in microwave systems.
2. Imaging based on microwave: utilization in tumor detection, target location and recover in imaging map, structural health monitoring.
3. Microwave field: field shaping, field control, transient field shaping, constant field shaping.
4. Wireless power transfer based on microwave.
5. Enhancement of any aspect of communication.
6. Wave design.
