Associate Professor / TAMAYAMA Yasuhiro
Driven by a passion for research, Prof. Tamayama fosters curiosity in his laboratory, creating a climate where every question leads to deeper knowledge. He encourages students to ask questions freely and provides concise, clear answers that promote understanding and growth. Prof. Tamayama is as supportive and kind to his students' research as to his own.
Research Content
Light (electromagnetic waves) plays an indispensable role in modern society, utilized in communication, measurement, and more. In this laboratory, we are developing technologies to control light with unprecedented precision using metamaterials, which are artificially engineered materials. Before the advent of metamaterials, control of light was achieved using natural substances (for example, glass lenses). However, the emergence of metamaterials, substances whose properties can be artificially designed, has opened up seemingly infinite possibilities for controlling light. Our laboratory designs metamaterials using electromagnetic field simulators, their fabrication and experimental testing.
Metamaterial structures: by designing the shape, the properties can also be freely designed.
A Day in the Lab
In our laboratory, we engage in theoretical analyses, electromagnetic simulations, and experiments at our own pace. We are required to independently formulate our research plans, which our supervisor then reviews and adjusts as necessary. This process ensures that our research progresses actively and smoothly. Weekly study sessions and research meetings are integral parts of our schedule, where we present and engage in in-depth discussions on our individual research projects. Additionally, the laboratory maintains core hours from 9:00 AM to 4:00 PM. During these hours, we are expected to conduct our research activities.
