Summary: This paper proposes a design for an optically transparent and dynamically tunable microwave-absorbing metasurface that enables dual modulations independently for two orthogonal linearly polarized excitations. The tunability is achieved by an anisotropic meta-atom composed of patterned graphene structure with dynamic and independent control of electromagnetic responses. Experimental measurements and circuit modeling demonstrate the dual tunability and physical relation between graphene's sheet resistance and polarization-independent modulations. The proposed metasurface enhances multitasking stealth performance in complex scenarios and has potential applications in advanced solar energy devices.

Summary: We propose a flexible transparent composite metamaterial structure that is compatible with microwave absorption in the radar band and low emissivity in the infrared. The structure includes radar wave absorber and infrared shield layers designed and fabricated on a transparent substrate using indium tin oxide material. The structure achieves 90% absorption over a wide frequency range, wide incidence angle stability, and maintains absorption of more than 90% over a polarisation range. The infrared emissivity of the structure is approximately 0.25. The design has application value for multi-spectral stealth and transparent electromagnetic shielding.

Summary: In this study, a transparent and flexible assembled metasurface rasorber supporting hybrid anapole states for infrared and microwave camouflage is proposed and experimentally demonstrated. It not only supports low IR emissivity in the range of 8-14μm, but also exhibits an absorption-transmission-absorption response in the microwave band. The conformal and tunable performances of the fabricated metasurface rasorber are experimentally demonstrated. This study provides a new strategy for designing multispectral camouflage metasurfaces.

Summary: This study proposes an optically transparent hybrid mechanism metasurface that incorporates absorption, polarization conversion, and phase cancellation mechanisms to achieve wideband, wide-angle, and omnidirectional scattering suppression. The metasurface design exhibits wideband, wide-angle, high-efficiency, and omnidirectional co-polarized scattering suppression performance. The phase cancellation mechanism further enhances the scattering suppression effect by distributing the unit cell and its mirror structure in a chessboard configuration. The proposed metasurface has significant radar cross section reduction and good optical transparency, with potential applications in multifunctional stealth design.

Summary: In this article, a compact and optically transparent metasurface radome with asymmetric electromagnetic absorption is proposed and demonstrated. It can be used to create low-radar cross section (RCS) and gain-enhanced multifunctional antennas. The metasurface has a bilayer structure consisting of periodically patterned and unpatterned transparent conductive films separated by a thin acrylic layer. Experimental results show that the microstrip antenna's realized gain can be increased by 6.1 dBi and its RCS can be reduced by more than 20 dB. The proposed bilayer metasurface has potential applications in next-generation radomes, self-powered 5G/6G base stations, satellite communication, and compact RF and microwave modules integrated with optical sensors, lidar, displays, and solar panels.

Summary: This study presents a transition from Q-switched state to continuous wave state in an erbium-doped fiber laser, accompanied by irregular mode-hopping. The results showed that the transition between these two states can be achieved by adjusting the pump power. Modulation peaks were observed on both the Q-switched pulse train and the continuous wave background, and the central wavelength fluctuated.
