Microwave Devices and Circuits Lab.

Shinichi Tanaka

We focus on developing state-of-the-art microwave function devices utilizing advanced circuit design technology based on metamaterial technology. Metamaterials* can be realized using circuit technology but for electromagnetic waves they behave like smart “materials” with properties that have not yet been found in nature. The new technology has been widely applied to passive microwave components, such as antennas, hybrid couplers and filters. Recently, we have proposed a new design method of metamaterial circuits, leading to high-performance, compact, and even low-cost design of active microwave components such as oscillators, amplifiers and rectifiers. This is crucial for microwave systems because the active components are the key to the overall performance, size and cost of the total system. Our recent achievements includes development of a triple-band rectifier for wireless power transmission or RF-energy harvesting systems [1], a low-phase noise oscillator for X-band radar systems [2], and highly efficient L-band power amplifier for cellular phone applications [3].

Networking and sensing through user terminal participation

Hiroaki Morino

We are interested in designing the next generation mobile network architecture and mobile computing systems. One of topics we are focusing on is realizing collaborative sensor networks by using user terminal participation, in which each user’s mobile terminal obtains live information from the real world by exploiting radio information or a variety of sensors equipped with them, and it uploads them to the server in the Internet to recognize the situation of the specific place. For example, we try to estimate crowd density at some place using users’ mobile phones, by that they obtain the signal strength and packet loss information of public WiFi access points there. We also address mitigating natural congestion that frequently occurs in highway through detecting congestion phenomena and sharing the congestion information by using vehicle ad hoc networks(VANET) and each car adjusts the velocity to reduce the congestion. The last example is assisting disaster relief. We address a method to record evacuation route trajectory of each person in indoor environment without GPS when the Internet is not available after the disaster occurs, by utilizing smartphone sensors such as acceleration sensors, gyro or air pressure sensors.
