(A) Top and rear views of 9/64, 21/64, 32/128, and 66/256 electrode configurations. (B) Basic structure of the BCI system. The 200 targets were formed by combining 40 square luminance-modulated ...

a, fabrication process of humidity-responsive CLCP films with geometric phase encoding. b, Photo of the films cured at 65℃. The scale bar is 1 mm. Sensing technology, integral to environmental ...

In CLC planar optics, this phase encoding alters the reflected light field across different wavebands, creating distinct visual patterns. This method surpasses traditional PBG wavelength/frequency ...
