| Outline of Final Research Achievements |
This research develops thermal imaging which visualizes the distribution of electromagnetic waves by observing temperature rise induced by absorption on a two-dimentional artificial structure, called metasurface. By imposing symmetry condition called self-complementarity on a checkerboard-like metasurface, efficient thermal imaging can be expected in broad spectral regions. The simulations, which compute heat induced by electromagnetic waves and its thermal diffusion, showed higher temperature rise in resistive sheets at the corners of the checkerboard structure compared with an uniform resistive sheet. In our experiment, which observed fabricated metasurfaces illuminated by microwave using a thermography, we observed significant temperature rise localized at the resistive sheets, and shown that the devise can be employed for effective and broadband thermal imaging.
