We study the propagation properties of an Airy beam through a four-level electromagnetic induced transparency (EIT) atomic vapor. The analytical expression for the Airy beam passing through the ABCD optical system of the EIT vapor is deduced and employed to analyze the propagation characteristics of the beam. It is shown that both the deflection position and the intensity of the Airy beam can be modulated by the Rabi frequency of the control light. Such a tunable optical behavior may have some potential applications in medicine science.

Terahertz frequency range imaging has become more and more attractive for a wide range of practical applications; however, further component optimization is still required. The presented research introduces 3D-printed high-impact polystyrene (HIPS) beam-shaping components for the terahertz range. Gaussian, Bessel, and Airy beam-shaping structures are fabricated, and different combinations are employed to evaluate imaging system performance.

Article Synopsis
- This study aimed to use a two-photon microscope excitation Airy beam to create detailed 3D images of intrahepatic bile ducts in mice with bile duct ligation (BDL) and human patients with biliary atresia (BA).
- Ten BDL mice showed symptoms like jaundice and weight loss, with liver tissues sampled after 10 days, while 16 BA patients underwent either liver transplantation or Kasai portoenterostomy (KPE).
- The imaging revealed significant bile duct widening and hyperplasia in BDL mice and disorganized bile ducts in BA patients, particularly those who had liver transplants.
This work presents the generation of an Airy beam by a leaky-wave structure (LWS) designed from a substrate-integrated waveguide (SIW) with dimension-varying slots. The Airy beam is radiated by judiciously designing the length of the slots to modulate the phase distribution. Compared to Airy beams generated by phased array antennas or metasurfaces, no complex feeding network associated with phase shifters and no space-wave illumination is required, thus allowing one to reach a low-profile structure.

The propagation characteristics of CABs modulated by the quadratic phase modulation (QPM) in a Kerr (cubic) nonlinear medium under power function diffractive modulation modes and parabolic potentials are numerically simulated by using a step-by-step Fourier method. Specifically, the threshold for CABs to form solitons in the Kerr medium is controlled by the Lévy index and the QPM coefficient.

Plasmons sustained by nanostructured conductors facilitate substantial interactions with free electrons, enabling considerable transverse modulation of the electron wave function. Consequently, electron Airy and vortex beams can also be produced through interactions between electrons and structured plasmonic fields.
