“…Additionally, they achieved significant birefringent behaviors for the Goos-Hänchen shifted beams. Recently, Li et al [42] proposed a time domain carpet cloak model by developing two new finite element schemes. Most recently, Ullah et al [43] investigated temporal cloaking under Compton scattering in a four-level atomic medium and have achieved temporal gaps in microseconds.…”

We theoretically explore the impact of cross-Kerr nonlinearity (CKN) on rotary photon drag (RPD) and temporal cloaking in a Sagnac interferometer. With the activation of CKN, signiﬁcant improvements in RPD and temporal cloaking are observed. Drag angles of ±1×10−3 and±5×10−3 radians are attained. Similarly, temporal gaps of 10µs, 12µs and 13µs are noticed. In addition to the observed electromagnetically induced transparency (EIT) window, group refractive index is drastically enhanced, time delay/advance are tuned from pico-radians to micro-radians, and reduced relativistic group velocities are achieved by activating CKN in the system. Additionally, the transmission pulses intensities are noticed to reduce with the dragging phenomenon. The ﬁndings may have potential applications in controlled image coding, rotation sensing and secure communication technologies.

“…Furthermore, the PML technique has been extended to solve other wave propagation problems in different media, such as acoustics, elastodynamics [2,14], elasticity [20], anisotropic dispersive media [6] and metamaterials [12,13,5]. Due to many potential applications of metamaterials such as design of invisibility cloaks, recently there has been a growing interest in the study of the Maxwell's equations involving metamaterials (e.g., [8,23,24,33]).…”

The original B´erenger’s perfectly matched layer (PML) was quite effective in simulating wave propagation problem in unbounded domains. But its stability is very challenging to prove. Later, some equivalent PML models were developed by B´ecache and Joly [4] and their stabilities were established. Hence studying and developing efficicent numerical methods for solving those equivalent PML models are needed and interesting. Here we propose a novel explicit unconditionally stable finite element scheme to solve an equivalent B´erenger’s PML model. Both the stability and convergence analysis are proved for the proposed scheme. Numerical results justifying the theoretical analysis are presented. We also demonstrate the effectiveness of this PML in simulating wave propagation in the free space. To our best knowledge, this is the first explicit unconditionally stable finite element scheme developed for this PML model.
