Chiral surface plasmon polaritons on metallic nanowires

S. Zhang
Institute of Physics CAS
Beijing
China

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate. En savoir plus

Simulation of chaotic mixing dynamics in microdroplets

H. Zhou, L. Jiang, and S. Yao
The Hong Kong University of Science and Technology,
Hong Kong

Rapid mixing is of essential importance in many microfluidic applications such as chemical reactions, drug delivery, sequencing or synthesis of nucleic acids, protein crystallization, etc. However, it is difficult to mix fluids in microchannels since flows in these channels are generally ...
