摘要: A method is presented for nano-patterning a diffraction grating on human hair with focused ion beam. Strands of brown hair are patterned hyperbolas and Archimedean spirals whose pitches range from 540 nm to 1040 nm. Exposure of the strands white light at various incident angles demonstrates that varying wavelengths diffracted by the gratings. The causes brown to reflect from entire range visible light.
