Summary: This paper presents a general approach to developing tunable plasmonic metasurfaces with hydrogel meta-atoms at the subwavelength scale. The size of hydrogel nanodots can be reversibly controlled by absorbing or releasing water, resulting in humidity-responsive surface plasmon polaritons (SPPs) that generate plasmonic color rendering in the visible spectrum. The size variations of constituent hydrogel nanostructures enable broadband beam-steering on a phase modulator.

Summary: This paper proposes a dynamically hybrid niching-based differential evolution algorithm (DHNDE) for solving multimodal optimization problems (MMOPs). The DHNDE algorithm achieves a good tradeoff between diversity and convergence by dynamically using two niching techniques, introducing a secondary archive, and improving the neighborhood speciation-based DE. Experimental results demonstrate that DHNDE provides highly competitive results compared to other methods, especially for MMOPs with a large number of global optima.

Summary: Anisotropy is important in various material systems, but creating and controlling it has been a challenge. Polarization-addressed anisotropy is attractive due to its controllability, simplicity, and accuracy, but only a few material systems can achieve it. In this study, a polarization-dependent anisotropic etching system made of Au@oligomer core-shell nanoparticles was established. The etching process is faster along the polarization direction, resulting in shape anisotropy of the particles. This system has advantages of high selectivity, controllability, and versatility, opening up new possibilities for on-chip nanofabrication.

Summary: This work introduces and demonstrates a method for tailoring multi-focus abruptly autofocusing beams in free space. It allows for direct and independent adjustment of the number, positions, and relative intensity of foci by controlling the design of abruptly autofocusing beams. The study also explores the relationship between the size of the light field and the characteristics of focus. By utilizing the double-phase hologram method, the required complex field is generated using a phase-only spatial light modulator in experiments, providing flexible control over the characteristics of foci and expanding potential applications of autofocusing beams.

Summary: In this study, a modified interfering vortex phase mask (MIVPM) is proposed to generate a new type of self-rotating beam. The MIVPM is based on a conventional and stretched vortex phase for generating a self-rotating beam that rotates continuously with increasing propagation distances. This study proves that this self-rotating array beam has an effectively enhanced central lobe and reduced side lobe owing to adding a vortex phase mask compared with a conventional self-rotating beam.

Summary: This paper presents a circular polarization-agile and continuous beam-steerable array antenna using a hybrid design approach. By combining digital reconfigurable antenna elements with analog continuously tunable phase shifters, both polarization reconfiguration and initial phase generation for beam scanning can be achieved simultaneously. The designed antenna element enables eight states corresponding to two circular polarization modes with four quantized phases, and the phase shifters provide additional variable phases for antenna element excitation. The ability to independently control circular polarization switching and beam scanning is obtained by altering the bias states of the electronic components loaded in the array antenna.

Summary: This work investigates the dynamically feasible point-to-point trajectory generation problem for a quadrotor flying through a constrained planner region known as a narrow gap. A four parameter logistic curve is considered as a potential candidate, and closed-form conditions are derived on the design parameters to satisfy the window traversability and vehicle dynamic feasibility constraints. A hierarchical approach is employed to compute a dynamically feasible design parameter set for decoupled trajectory components, and a solution set satisfying 3-D axis-coupled window traversability conditions is obtained. Numerical examples and comparative study validate the analytical findings, highlighting the quick computation of dynamically feasible window traversing trajectories in complex window scenarios.

Summary: This study investigates the existence, bifurcation, and stability of two-dimensional optical solitons in the context of the fractional nonlinear Schrodinger equation. Different scenarios of bifurcations are observed depending on the stability and type of nonlinearities, with asymmetric solitons emerging through symmetry breaking bifurcation. The restoration or destruction of symmetry in antisymmetric solitons can be controlled by adjusting the fractional diffraction in the case of self-defocusing saturable nonlinearity.
