TL;DR: Toroidal moments are fundamental electromagnetic excitations that cannot be represented in terms of the standard multipole expansion as mentioned in this paper, but only recently have become the subject of growing interest owing to their peculiar electromagnetic properties Electromagnetic interactions with toroidal currents were predicted to disobey such widely accepted principle as the action-reaction equality.

TL;DR: In this article, the authors demonstrated three achromatic meta-lens based on IRUs designs to show constant focal length in the range of 400 to 650 nm and a broadband versatile polarization generator operating in 400 nm to 1300 nm.

TL;DR: The functionalities of traditional optical component are mainly based on the phase accumulation through the propagation length, leading to a bulky optical component like lens and waveplate as discussed by the authors, thus, traditional optical components are mainly used for phase accumulation.

TL;DR: In this article, a liquid waveguide with dispersing gold nanoparticles (Au NPs) in a micro-channel is presented, which can combine the unique properties of Au NPs with the guiding and scattering of light along the microchannel.

TL;DR: Development of imaging, sensing, and characterization of cells at Research Center for Applied Sciences (RCAS) of Academia Sinica in Taiwan is progressing rapidly, and new microfluidic cell culture devices for fast and accurate characterizations prove various diagnosis capabilities.
