TL;DR: A novel approach for designing richer Fourier spectra is introduced, by using a periodic structure that allows us to control its Fourier components almost at will, and it is shown how these structures can be employed to achieve highly efficient broad-band light trapping in thin films that approach the theoretical limit.

TL;DR: In this article, a planar bidentate ligand and two twisted bipy ligands with torsional angles between each bipyridine were used to construct the complex.

TL;DR: In this article, the binding properties of the two complexes to calf thymus DNA has been investigated with spectrophotometric methods and viscosity measurements, and the experimental results indicate that the complexes bind to DNA through a partial intercalative mode that is different from the bonding mode for their parent compound, [Ru(bpy)2(PIP)]2+ (PIP=2-phenylimidazo[4,5-f]1,10-phenanthroline).

TL;DR: This work introduces and demonstrates a metalens with a high NA and high transmission in the visible range, based on crystalline silicon (c-Si), and envision the front-immersion design to be beneficial for achieving ultrahigh-NA metalenses as well as immersion metalens doublets, thereby pushing metasurfaces into practical applications such as high resolution, low-cost confocal microscopy and achromatic lenses.

TL;DR: A highly symmetric excitation optical field and optimized detection scheme are proposed to harness the total point-spread function for a microscopic system, showing that the proposed scheme provides a better image quality.
