Polarization-mismatching transmissive metasurface for independent amplitude and phase control of circular polarization.

This work presents a strategy for independent control of the amplitude and phase of transmissive circular-polarization (CP) waves. The designed meta-atom consists of an elliptical-polarization receiver and a CP transmitter. By changing the axial ratio (AR) and polarization of the receiver, amplitude modulation can be realized based on polarization mismatching theory, with negligible cumbrous components.

[A technique for investigating the component of cantharidin blisters by flow cytometry].

Objective: Cantharidimide cause blister. The effect of blister on immunoregulation was investigated.

Methods: Cantharidimide was placed on the skin, 48h later, the blister was analyzed by flow cytometry.
