Summary: This article investigates the effects of random arrangement of layers, length of the multilayer, and chemical potential of graphene on the robustness of the graphene induced photonic bandgap (GIPBG) in one dimensional graphene-embedded photonic crystals. Numerical results show that the random arrangement and length of the multilayers cause minor changes in the bandgap edge, while the chemical potential strongly affects the robustness of the low frequency GIPBG.

Summary: This study achieved comprehensive exceptional energy storage performance in Na0.5Bi0.5TiO3-Sr0.85Bi0.1TiO3 (NBT-SBT)-based ceramics through stepwise optimization by substituting Bi(Mg0.5Sn0.5)O-3 (BMS) and optimizing the formation process. The introduction of Mg2+ and Sn4+ ions at the B-site induced polar nanoregions, and the viscous polymer process (VPP) improved the polarization difference and breakdown strength. As a result, the ceramics exhibited ultrahigh energy storage density and high efficiency, along with excellent temperature adaptability.

Summary: This study analyzes the electrokinetic response of nanoparticles suspensions coated with a shell of polyelectrolyte under the action of alternating electric fields. The use of electrokinetics helps to characterize the coating in situ in order to control the stability and functionalization of the particles. AC electrophoresis and dielectric dispersion techniques are evaluated to provide rich and rigorous information on various parameters such as particle size, charge, thickness, and rigidity. The results showed that the brush-like structure of the polyelectrolyte coating enhanced the mobility and stability of the particles compared to the soft coating.

Summary: This study proposed a model of oblique wave diffraction by multiple arbitrary porous barriers in infinitely deep water to investigate the role of porous breakwaters in mitigating wave effects and dissipating wave energy. The analysis showed significant changes in wave reflection and forces when considering porous barriers compared to rigid barriers, with a decrease in wave load as the number of barriers increased. Additionally, increasing the permeability of the barriers resulted in more energy dissipation.

Summary: In this letter, a frequency selective absorber with enhanced angular stabilities, called DML-FSR, is introduced. It consists of a dielectric matching layer (DML), a lossy layer, and a lossless layer to generate absorption and transmission bands. The simulation and measurement results show that DML-FSR has wide transmission and absorption bands with good stabilities under different incident angles. It has potential applications in stealth radar platforms and anti-interference systems.

Summary: This study investigates the influence of the deposition process of ZnO thin films grown on glass and silicon substrates by atomic layer deposition (ALD) technique on their morphology, optical properties, AC conductivity, and dielectric properties. The atomic structure of the ZnO film is analyzed using SEM, EDX, and XRD. The study also explores the relationship between optical energy gap (E-g), refractive index (n), and deposition condition. Electrical parameters such as dielectric characteristics and AC conductivity are estimated and the conduction mechanism is examined. This article presents recent advances in ALD-modified ZnO metal oxide, which has potential applications in sensor device fabrication.

Summary: With the development of 5D seismic technology, stable acquisition of anisotropy information from wide-azimuth seismic data has become a key scientific problem. The conventional AVAZ inversion method suffers from too many parameters and inversion instability, so an AVAZ inversion method with coherence-attribute constraints is developed to solve these problems.

Summary: This article presents a comprehensive theory for synthesizing a dispersive box coupling section to control two transmission zeros (TZs) and applies it to the design of high-Q monoblock dielectric resonator (MDR) filters. The dispersive box section offers advantages over the traditional cascaded quadruplet (CQ) MDR section, including greater flexibility in controlling TZs, a wide spurious-free high rejection band, simplicity in physical realization, and higher unloaded Q factors. The article discusses the circuit realizations of all possible TZ arrangements and presents a practical eight-pole MDR filter that demonstrates excellent agreement between the synthesized and measured responses. The low in-band insertion loss suggests that MDR filters using the dispersive box structure have potential applications in 5G and future wireless communication systems.

Summary: This article introduces a dispersive quadruplet structure that can flexibly control the rejection response of a high-Q monoblock dielectric resonator (MDR) filter using a shared cavity. By managing metalized through holes, the dispersion effect of the blind hole can be effectively compensated and the rejection response can be controlled to a certain extent. The article also provides a mathematical transformation and design guidelines to explain the working principle and guide the design. Experimental results demonstrate the practicality of this structure when rejection specifications near the passband are stringent.

Summary: A switchable frequency selective surface is designed in this study, which can switch between absorber and rasorber operation with wide passband characteristics. The structure is built on a single dielectric layer with lossy and lossless layers on opposite sides. Wideband absorption from 4.8 to 15 GHz is achieved through lumped resistors in the lossy layer, while PIN diodes in the lossless layer enable the structure to operate as a rasorber. The structure is immune to polarization and angle sensitivity, and the fabricated prototype shows good agreement with simulated results. The proposed design is expected to have applications in various airborne technologies.

Summary: A novel optical frequency-hopping scheme using a dual-drive Mach-Zehnder modulator (DD-MZM) is proposed and demonstrated for secure transmission in fiber-optic networks. The proposed scheme utilizes the phase difference between RF signals loaded on the two arms of the DD-MZM and filtering techniques to achieve random hop between the positive and negative sidebands, serving as carriers for data modulation. Simulation results show error-free transmission through 40 km fiber with 10 Gbps hopping rate and 10 Gbps data rate. Theoretical evaluation also demonstrates the high security performance of the proposed scheme.
