Abstract The Aira caldera, located in southern Kyushu, Japan, originally formed 100 ka, and its current shape reflects the more recent 30 ka caldera-forming eruptions (hereafter, called the AT eruptions). This study aimed to delineate the detailed tw

Abstract In 2018, a phreatic eruption occurred at Mt. Motoshirane, a pyroclastic cone group of the Kusatsu-Shirane Volcano in central Japan. The eruption was abrupt, and no signs of volcanic activity have been observed in recent years, in contrast to

Seismic exploration was conducted along a profile running through the Aira caldera located in southern Kyushu, Japan. The caldera was formed by an ignimbrite eruption approximately 30 ka BP, namely, the “AT eruption,” which produced the Ito ignim

Rotational varifocal moiré metalens made of single-crystal silicon meta-atoms for visible wavelengths
Autor: Chikara Ogawa, Sotaro Nakamura, Takumi Aso, Satoshi Ikezawa, Kentaro Iwami
Publikováno v: Nanophotonics. 11:1941-1948
Metasurface lenses (metalenses) offer an ultrathin and simple optical system with dynamic functions that include focal length tuning. In this study, a rotational varifocal (i.e., moiré) metalens based on octagonal single-crystal silicon pillars was

Demonstration of a multicolor metasurface holographic movie based on a cinematographic approach
Autor: Naoyuki Yamada, Hiroki Saito, Satoshi Ikezawa, Kentaro Iwami
Publikováno v: Optics express. 30(10)
This study uses a dielectric metasurface to demonstrates a multicolor holographic movie. Overlapping of multiple-wavelength images at 445 nm, 532 nm, and 633 nm was achieved by maintaining the ratio between the wavelengths and the pixel periods const
