Dielectric cross-shaped resonator based metasurface for vortex beam generation in Mid-IR and THz wavelengths
Raghu Dharmavarapu, Ken-ichi Izumi, Ikufumi Katayama +7
Metasurfaces are engineered thin surfaces comprising two dimensional (2D) arrays of sub-wavelength spaced and sub-wavelength sized resonators. Metasurfaces can locally manipulate t…
Nanoscale optical and structural characterisation of silk
Meguya Ryu, Reo Honda, Adrian Cernescu +10
Background: Nanoscale composition of silk defining its unique properties via a hierarchical structural anisotropy has to be analysed at the highest spatial resolution of tens-of-na…
Paracetamol Micro-Structure Analysis by Optical Mapping
Reo Honda, Meguya Ryu, Armandas Balcytis +4
Domain structure of paracetamol -- popular antipyretic analgesic -- was investigated by infrared (IR) spectroscopy using synchrotron radiation. Absorbance and retardance maps revea…
Nanoscale chemical mapping of laser-solubilized silk
Meguya Ryu, Hanae Kobayashi, Armandas Balcytis +8
A water soluble amorphous form of silk was made by ultra-short laser pulse irradiation and detected by nanoscale IR mapping. An optical absorption-induced nanoscale surface expansi…
Orientational Mapping Augmented Sub-Wavelength Hyper-Spectral Imaging of Silk
Meguya Ryu, Armandas Balcytis, Xuewen Wang +6
Molecular alignment underpins optical, mechanical, and thermal properties of materials, however, its direct measurement from volumes with micrometer dimensions is not accessible, e…
