This work presents a theoretical investigation of a simple yet novel photonic crystal fiber (PCF) biosensor, which utilizes principle of surface plasmon resonance (SPR) effect. The numerical characterization was done using the finite element method (FEM) through COMSOL Multiphysics software. As the active plasmonic material Indium tin oxide (ITO) is used at the outer surface of the PCF-based biosensor. The air-holes orientation within the PCF resembles the shape of “X”, which is designed to enhance the phase matching between the core-guided mode and the plasmonic mode. The operating region of the sensor is near-infrared (1400 – 2000 nm), for the analyte refractive index range between 1.32 and 1.36. Wavelength sensitivity of 12,000 nm/RIU and amplitude sensitivity of 231 RIU−1 is achieved with the high resolutions of 8.33×10−6 RIU. The proposed biosensor is suitable for accurate sensing applications of detecting unknown RI in the field of biological analyte detections.

Visible light communication (VLC) schemes provide high data rate communication using orthogonal frequency division multiplexing (OFDM). VLC can be impaired by side effect modulation (SEM) which is the unintended modulation caused by the power supply to manage the LED luminaires. In the literature, the impact of SEM has already been illustrated for DC-biased optical OFDM (DCO-OFDM) and asymmetrically clipped optical OFDM (ACO-OFDM). However, the impact has not been analyzed for any hybrid optical OFDM formats. This paper evaluates the influence of SEM for a hybrid optical OFDM termed as asymmetrically clipped DC-biased optical OFDM (ADO-OFDM). Our results show that a very small amount of SEM can remarkably decline the bit error rate (BER) performance of ADO-OFDM. It is found that the degradation due to SEM is more in ADO-OFDM compared to DCO-OFDM and ACO-OFDM. In the mitigation process, we estimated the SEM signal by subtracting the transmitted signal from the random average received signal, and then deducting the estimated SEM from the sampled received signal. Results show that the mitigation process greatly improves the BER performance of ADO-OFDM based VLC systems.

Modern technology has brought the Internet of things (IoT) which is a blessing for the nearly 8 billion people in the world. Using the advancement of IoT, we need not stay at our home all the time to use our appliances because IoT gives us a choice to use them from anywhere. Transferring and receiving data from one device to another becomes too easy with the remote monitoring process as IoT connects all the devices to the internet. But IoT infrastructure can be affected by a couple of different attacks and anomalies as it uses IoT sensors and wireless devices. As the public shares lots of their confidential and private data, it is necessary to establish user security and privacy by detecting intrusions and malware in this infrastructure. In this paper, 5 different supervised machine learning algorithms K Nearest Neighbors (KNN), Naive Bayes, Support Vector Machine (SVM), Random Forest, and Decision Tree Classifier have been used to detect attacks in different computer networks which are listed in CICIDS 2017 dataset. The paper shows the novel approach of detecting new attacks by extracting the highest weight scored 25 features using Random Forest Regressor and Extra Tree Classifier to analyze different cyberattacks by implementing different supervised learning models. After performing a comparison analysis between the 5 algorithms the paper finds that the KNN model performs better than others by giving the highest F1 score and accuracy.
现代科技带来了物联网(IoT)，这是全球近80亿人的福音。利用物联网的进步，我们不需要一直呆在家里使用我们的电器，因为物联网让我们可以选择在任何地方使用它们。随着物联网将所有设备连接到互联网，远程监控过程将数据从一个设备传输和接收到另一个设备变得太容易了。但物联网基础设施可能会受到几种不同的攻击和异常的影响，因为它使用物联网传感器和无线设备。由于公众共享了大量的机密和私人数据，因此有必要通过检测该基础设施中的入侵和恶意软件来建立用户的安全和隐私。本文使用5种不同的监督机器学习算法K最近邻(KNN)、朴素贝叶斯(Naive Bayes)、支持向量机(SVM)、随机森林(Random Forest)和决策树分类器(Decision Tree Classifier)来检测CICIDS 2017数据集中列出的不同计算机网络中的攻击。本文展示了一种检测新攻击的新方法，通过使用随机森林回归器和额外树分类器提取权重得分最高的25个特征，通过实现不同的监督学习模型来分析不同的网络攻击。在对5种算法进行对比分析后，本文发现KNN模型的F1得分和准确率最高，优于其他算法。

A plasmonic nanotweezer with a diabolo hollow notch (DHN) structure is proposed by adding a metal thin film at the bottom of a metal diabolo aperture (DA) nanostructure. The bottom metal film enables the nanotweezer to utilize screening effect and accumulate more free charges near the central corners of the top surface. Consequently, enhanced electric field enables the nanotweezer to trap particles near the top surface when incidented with relatively low-power beam. Silver (Ag) was selected as the metal due to the fact that Ag is much cheaper than gold (Au). Moreover, Ag provides similar thermal conductivity compared to Au. Thus, cost-effective Ag based DHN nanostructure can dissipate heat from the hot region quickly while avoiding particle damage and thermophoresis. Additionally, Ag offers greater reflectivity which can further enhance the screening effect. In this work, we analyzed optical properties of Ag DHN nanotweezer based on structural parameters and proposed an optimized design for efficient nanoparticle trapping. Based on our analyses, the proposed nanotweezer had trapping stiffness (kx, ky, kz) of ~13.7, ~15.4, and ~96 fN/nmWμm−2, respectively. Moreover, Ag DHN nanotweezer can trap a polystyrene sphere of 100 nm diameter with minimum source intensity of 1.9 mWμm−2 which is 66% lower than that required for Ag DA nanotweezer.

In this paper, we proposed a hollow core antiresonant fiber, having conjoined tube cladding elements with additional negative curvature layer which presents hybrid configuration, offers very stunning performance among related fibers. The proposed hybrid conjoined tube fiber exhibits a lowest loss of 3.0×10−6 dB/m at 1430 nm by keeping a loss of ~ 4.0×10−5 dB/m over the ample bandwidth of 300 nm. It leads to a minimum surface scattering loss of 2.0×10−5 dB/m and a minimal microbending loss of 4.0×10−5 dB/m resulting in a total loss of 1.0×10−4 dB/m at 1550 nm. The proposed fiber also presents a bending loss of 1.0×10−5 dB/m at the bend radius of 7 cm along with better single mode performance having the higher order mode extinction ratio of ~ 1600 and keeps larger than 100 over the wavelength of interest. The proposed fiber may have the potential application in telecommunication systems for its promising performances.

In this work we compare the prospect of detecting virus-like particles using single and multiple arrays of rotationally symmetric array of silicon nanowires. Taking the dimension and geometry of the Coronavirus as a reference, resonant wavelength shift and quality factor change of the whispering gallery mode of the nanowire array in the presence of one and two viruses are evaluated employing finite difference time domain analysis technique. For a single coronavirus having protein spike, the maximum shift of resonant wavelength is found to be about 5 nm, whereas for two viruses the shift can be as high as 9 nm. However, interestingly, for two viruses the shift appear to change periodically depending on relative location of the virus particles. As far as multiple arrays for virus detection is concerned, the quality factor of the most strongly confined whispering gallery mode appears to have been reduced by 50% or more because of mode-leakage resulting from coupling between the nanowire arrays. Such weaker confinement of the optical field though may have a diminishing effect on the signal to noise ratio during practical measurements, the detection sensitivity appears to have improved significantly because of the sustenance of whispering gallery resonant modes in the adjacent nanowire arrays.

This paper presents a self-oscillating active integrated array antenna (AIAA) constructed with two radiating patches. The proposed AIAA has two patch antennas to act as radiators, and a Gunn diode as an active source. Besides, a simple biasing network using shorted stubs and a slit is designed for the Gunn diode without requiring any external circuitry. The performances of the antenna are examined experimentally. The measured results show an effective isotropic radiated power (EIRP) of +5.8dBm with a transmitted power of −5.6dBm at 9.54 GHz. The measured cross-polarization suppression is more than 20 dB. Moreover, a concept of beamwidth controllability employing the proposed array antenna is discussed and confirmed by simulation.
