Waves include electromagnetic waves such as radio waves and light, sound waves, and gravitational waves. There are millimeter waves and terahertz waves in the boundary area between radio waves and light, and their use in smartphones and IoT has been considered in recent years. In order to utilize this undeveloped frequency, a new technology “wave engineering” that flexibly controls waves is important. For example, controlling the phase to form a beam in the desired direction or switching to a better wavelength in the propagation environment. In our laboratory, we are researching innovative analog integrated circuits for freely controlling the frequency, phase, and amplitude of waves. Through this research, we aim to realize highspeed wireless communication that can be connected without interruption, and to realize sensing and imaging such as food analysis, lesion analysis, and space exploration. In the 6th generation mobile communication system (6G) era, the area of information communication extends not only on the ground but also in the sky, underwater, and space. We will enrich our lives with circuit technology.
