We propose a meta-hologram for generating an abruptly autofocusing ring-Airy beam in the Terahertz (THz) band. The designed meta-hologram is composed of gold C-shaped slot antennas, which can be used to modulate the phase and amplitude of the scattered THz wave. A THz ring-Airy beam is generated and observed. The propagation process is also investigated in detail. This method can be expanded to other...
A data acquisition system is designed for biosensor based on nanopore, used the chip of TI TMS320VC5509A and Cypress Cy7C68013A. The major goal for our system is to convert analog data to digital data and transfer data to computer. Our system can be used in biological signal data convert already. The experimental results already proved the availability of the system. Because of using of the DSP chip...
