Supervisor

Associate Professor / Yasuhiro TAMAYAMA
When we are ask Prof. Tamayama a question, he gives us a logically clear answer, even if the question has no relation to our research. Because he thinks that it is important for us to actively act, he lets us make a research at our own pace.

Research Content

We develop methods for controlling electromagnetic waves using metamaterials consint of subwavelength structures. Metamaterials enable us to realize electromagnetic properties that do not exist in nature and to control propagation of electromagnetic waves in exotic ways. There are many applications using electromagnetic waves, therefore, developing techniques for controlling electromagnetic waves using metamaterial would be useful for our lives.

Experimental setup for controlling microwaves using metamaterials.

A Day in the Lab

Core time is provided in our laboratory,AM9:00-PM4:00. We must participate in a study session on research meeting, which are held once a week, respectively. In the research meeting, we present and deeply discuss our own research. In other times, we make theorical analyses, electromagnetic simulations and experiments at our own pace. We must make our research plan for ourself, while the supervisor properly modifies the plan as needed. This lets us make a research actively and smoothly.
