Summary: Aircraft's infrared (IR) signature modeling has been studied recently with a focus on thermal-flow characteristics and emissivity control for IR camouflage. However, limited studies have analyzed the camouflage effect of applying IR camouflage material to the aircraft surface based on surface temperature distributions or finding suitable surfaces for effective camouflage. This article describes the impact of componential signature reduction on aircraft's susceptibility to IR-guided missiles using multiband detection. Computational fluid dynamics simulations were used to analyze the thermal-fluid characteristics, and IR signature levels were calculated based on surface temperature distributions in mid and long-wavelength bands for susceptibility analysis. Based on the surface temperature distribution and IR signature level, the aircraft surface was classified into different categories. The article expects to contribute to the advancement and realization of IR camouflage in actual flight conditions.

Summary: In this study, a lead-free pyroelectric infrared (PIR) detector using (Bi1/2Na1/2TiO3)-BaTiO3(BNT-BT) ferroelectric ceramics as the sensitive material was investigated. The effects of modulation frequency on noise density, voltage response rate (R-V), and specific detection rate (D*) under the current mode amplification circuit were studied. It was found that the lead-free PIR detector exhibited high R-V in the low frequency band. The R-V and D* reached 1.51 x 10(5) V/W and 2.02 x 10(8) cmHz(1/2)W(-1) at 10 Hz, respectively. The results indicated that BNT-BT lead-free ceramics have great potential in PIR detector applications.

Summary: RF SAW resonators are widely used in mobile phones, but the need for an accurate and fast simulation method is urgent. Current limitations in computer memory and speed make it difficult to characterize the behavior of the entire acoustic resonator, especially for SAW resonators with long arrays of IDTs. This paper extends a previously reported PDE model based on 2D-FEM to analyze the periodic structure of SAW resonators, using MOR techniques to maintain computational accuracy.

Summary: This article presents a general-purpose model based on piezoelectric constitutive equations combined with perturbation theory and full finite element method (FEM) for efficient and accurate calculation of third-order nonlinear signals in surface acoustic wave (SAW) devices. The model is validated by simulating third-order harmonic (H3) responses and intermodulation distortions (IMD3) in SAW resonators, and the results fit well with experimental data. Furthermore, the generation mechanisms of the third-order nonlinearity in SAW resonators are discussed, and the dominant mechanisms for different nonlinear signals, as well as the relation between electrode materials and H3 peak magnitude, are revealed, providing important guidance for further nonlinear suppression.

Summary: Thermal interface materials (TIM), represented by submicron silver adhesive, offer a promising solution for ultra-high heat dissipation in chip integration. However, accurately characterizing the thermal performance of submicron silver adhesive interfaces and understanding their high-temperature degradation mechanism remain challenging. In this study, accelerated high-temperature aging experiments are conducted on submicron silver adhesion interfaces, and a non-destructive testing method is developed to measure the degeneration of interfacial thermal resistance (ITR). The microstructural evolution of silver adhesive interfaces is analyzed using scanning electron microscopy and X-ray microstructural analysis, and a three-stage degradation process of ITR is identified. Additionally, a physical model is proposed to explain the degradation mechanism of ITR at high temperatures. This work contributes to the advancement of submicron silver's application as a high-performance TIM.
