In the field of Internet, an image is of great significance to information transmission. Meanwhile, how to ensure and improve its security has become the focus of international research. We combine DNA codec with quantum Arnold transform(QAr T) to propose a new double encryption algorithm for quantum color images to improve the security and robustness of image encryption. First, we utilize the biological characteristics of DNA codecs to perform encoding and decoding operations on pixel color information in quantum color images, and achieve pixel-level diffusion. Second, we use QAr T to scramble the position information of quantum images and use the operated image as the key matrix for quantum XOR operations. All quantum operations in this paper are reversible, so the decryption operation of the ciphertext image can be realized by the reverse operation of the encryption process. We conduct simulation experiments on encryption and decryption using three color images of “Monkey”, “Flower”, and “House”. The experimental results show that the peak value and correlation of the encrypted images on the histogram have good similarity, and the average normalized pixel change rate(NPCR) of RGB three-channel is 99.61%, the average uniform average change intensity(UACI) is 33.41%,and the average information entropy is about 7.9992. In addition, the robustness of the proposed algorithm is verified by the simulation of noise interference in the actual scenario.

An ultra-wideband circularly polarized microstrip patch antenna loaded with split-ring resonator

引用

Optoelectronics Letters 2025年

作者： wang Shike XIA Dan Lü Lianrong QIN Juan wang Meng ren Haiping School of Integrated Circuit Science and Engineering， Tianjin University of Technology

In this paper， the effect of a single-opening split-ring resonator （SRR） structure on the performance of ultra-wideband （UWB） microstrip patch antenna （MPA） is studied. Here a UWB MPA based on partial grounding is proposed， and the SRR structure is utilized to optimize other characteristics of the low-profile microstrip antenna while ensuring the bandwidth and gain remain unchanged. The proposed metamaterial structure， consisting of a 2 × 2 array of SRR， is loaded on the reverse side of the substrate. The volume of the proposed antenna is 61.6×67.6×1.5mm3. According to simulation and experimental results， the proposed microstrip antenna loaded with 2×2 SRRs performs better than that without SRR structure. It produces an operating band of 1.62 GHz-8 GHz while achieving circular polarization characteristics with an axial ratio （AR） bandwidth of 3.92 GHz-4.57 GHz. In addition， the performance of the proposed antenna is superior to relevant works of literature The antenna can be widely utilized in wireless communication systems.

为探究平面集成瞬态抑制二极管(TVS)对半导体桥(SCB)火工品换能元性能的影响因素以及规律,通过电容放电发火实验,研究了平面集成TVS二极管的并联数量与击穿电压对半导体桥火工品换能元的电爆性能的影响,并通过500 pF/500Ω/25 kV静电放电实验,研究了其对半导体桥火工品换能元的静电可靠性能的影响。结果表明,当激励能量使单个平面集成TVS二极管单位时间吸收的能量接近上限时,增加平面集成TVS二极管并联数量会延长SCB火工品换能元的爆发时间,影响SCB火工品换能元正常爆发,反之,若激励能量不足以使单个平面集成TVS二极管单位时间吸收的能量接近其上限,则SCB火工品换能元爆发性能不会随并联平面集成TVS二极管的数量变化而变化;当激励电压大于平面集成TVS二极管的击穿电压时,TVS二极管击穿电压越低,SCB火工品换能元的爆发时间越长,爆发能量越大,甚至影响SCB火工品换能元正常爆发;降低平面集成TVS二极管的击穿电压、增加并联数量都能够提高SCB火工品换能元的静电可靠性能;设计桥区尺寸为350μm(W)×100μm(L)×2μm(H)的抗静电集成半导体桥芯片时可以集成两个击穿电压略低于14 V或一个击穿电压略高于7 V的TVS二极管。

Improving cutoff frequency estimation via optimized π-pulse sequence

引用

Chinese Physics B 2025年第1期34卷 273-278页

作者： wang-sheng Zheng Chen-Xia Zhang Bei-Li Gong School of Electrical Engineering Guangxi UniversityNanning 530004China Faculty of Science and Technology College of Arts and Sciences of Hubei Normal UniversityHuangshi 435109China

The cutoff frequency is one of the crucial parameters that characterize the environment. In this paper, we estimate the cutoff frequency of the Ohmic spectral density by applying the π-pulse sequences(both equidistant and optimized)to a quantum probe coupled to a bosonic environment. To demonstrate the precision of cutoff frequency estimation, we theoretically derive the quantum Fisher information(QFI) and quantum signal-to-noise ratio(QSNR) across sub-Ohmic,Ohmic, and super-Ohmic environments, and investigate their behaviors through numerical examples. The results indicate that, compared to the equidistant π-pulse sequence, the optimized π-pulse sequence significantly shortens the time to reach maximum QFI while enhancing the precision of cutoff frequency estimation, particularly in deep sub-Ohmic and deep super-Ohmic environments.
