This article deals with an original equalization method of 3-D electromagnetic (EM) cavity resonance by using bandpass negative group delay (NGD) function. Based on the equivalent circuit, S -matrix model equalized EM is introduced. The design equations NGD function are established in physical ...

We show that strong squeezing and entanglement can be generated at the output of a cavity containing atoms interacting with two fields in a coherent population trapping situation, on account of a nonlinear Faraday effect experienced by the fields close to a dark-state resonance in a cavity. Moreover, the cavity provides a feedback mechanism allowing to reduce the quantum fluctuations of the gro...

In this paper, cavity-excited Huygens’ metasurface is proposed for high-efficiency wavefront manipulation. By adjusting the length of electric dipole and magnetic , meta unit can provide nearly 360° phase coverage with sufficiently high transmission efficiency. Based on analysis resonance mode cavity, has successfully performed its function by adopting integrated feeding method. According to ge...
