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

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 ...

This paper presents a novel design of single-bit RF MEMS phase shifter. The basic novelty introduced for phase shifter design in this case, is by scaling down of the lateral dimensions of the conventional RF MEMS shunt switch by 10 times. The Mechanical and Electromechanical analysis ... En savoir plus

COMSOL Multiphysics 4.0 is being used to simulate the free vibrations of a plate. The results obtained by simulation in COMSOL are in close proximity to that found by Fast Fourier Transform analyzer and analytical method. As of now the vibration analysis of thin rectangular plates with ... En savoir plus
