To possess circular polarization (CP) fields, a unique antenna element composed of rectangular dielectric resonators (RDR) coupled with octagonal slots (OS) at the ground plane and excited by the mean of a microstrip feed at the front plane is proposed. The proposed resonating element generates two orthogonal modes, <span>(TE_{delta 2 1}^{x})</span> and <span>(TE_{ 1 delta 1}^{y})</span>, ensuring the existence of CP performance. To obtain a DCP performance, the proposed resonator is utilized for portraying a seven-element array employing a concentric ring fed with dual differential port excitation. The concentric ring fed allows choosing the direction of the input wave and, accordingly, the orientation of the CP. Hence, synchronous feeding to both ports yields in generating waves of various polarization states.

Its characteristic nonlinear function is simplified to make it suitable for digital hardware implementation. In this process, the modified model must best reflect the dynamic behavior of the original one and the error must be determined as accurately as possible. Based on this requirement, the error between the original and modified CN models is calculated by utilizing their spike timing differences and these differences are determined using the “median + K × Median Absolute Deviation (MAD)” method. On the other hand, since the simplification is required to enable easier implementation with digital hardware, it is necessary to demonstrate the feasibility of the implementation and to determine the associated hardware cost. For this purpose, the modified CN model is implemented using a FPGA device. The electrical output signals are recorded with an oscilloscope, and these signals are analyzed through the “Recurrence Quantization Analysis (RQA)” method to assess the neural diversity of the modified model.

This method utilizes the characteristic parameters provided by the manufacturer, such as short-circuit current, open-circuit voltage, and current and voltage at the maximum power point, to construct a smooth theoretical I–V curve of HIT cells through piecewise Pivora function fitting. It replaces the measured curve that is susceptible to interference, reduces the impact of measurement errors on the identification results, and achieves the purpose of accurately modeling the I–V curve of HIT cells without experiments. Experimental results show that the average errors of the theoretical I–V curve are only 0.55% and 0.81%, indicating high fitting accuracy. Subsequently, MSDCOA is adopted to solve the optimal parameters of HIT solar cells. Compared with traditional intelligent optimization algorithms, the root mean square error of parameter identification by MSDCOA is as low as 0.005519, 0.008483, 0.009900, and 0.009917, respectively, showing better performance.

Vacuum-referenced band edges were then constructed through a material-specific vacuum-referenced band-edge partition model to determine band offsets and junction electrostatics. Over 0–9 GPa at 300 K, the band gaps increase from 3.393 to 3.625 eV for GaN and from 3.396 to 3.616 eV for ZnO, leading to a blue shift in the UV cutoff wavelength from about 365 nm to 342 nm.

The structure preserves a Type-II band alignment under compression with moderate offsets of about 0.11–0.15 eV. After including material-specific band-edge partitioning, pressure-dependent dielectric response, explicit density-of-states parameters, and screened polarization charge, the built-in potential increases from 3.093 to 3.295 V, while the peak junction electric field increases from 862.8 to 1110.0 kV/cm.

Through-silicon vias (TSVs) serve as essential interconnects in 3D integration technology. However, numerous design challenges arise with TSVs. Furthermore, TSVs can significantly contribute to noise throughout the substrate. Consequently, noise coupling from TSVs is regarded as a critical factor in the design of 3D ICs. This paper presents an in-depth analysis of noise induced by TSVs, examining various key design parameters. The performance of structures utilizing carbon nanotubes (CNTs) and graphene as core materials for TSVs was evaluated in terms of noise coupling reduction. Furthermore, the noise isolation effectiveness of a p + guard ring around the signal TSV in 3D ICs is verified using the TSV noise coupling model. The impact of the proposed shielding techniques was evaluated in both the frequency and time domains. Additionally, noise coupling from TSVs to the silicon substrate was examined with various liner materials, such as silicon dioxide (SiO<sub>2</sub>), benzocyclobutene (BCB), Teflon, and Perylene-N. In comparison to traditional copper (Cu)-filled TSVs, the results show that graphene nanoribbon (GNR) and CNT based TSVs greatly reduce substrate and inter TSV noise. While time domain data indicate a decreased peak substrate noise voltage, frequency domain analysis indicates an improvement in forward transmission. Noise isolation is further improved by the addition of a p + guard ring and optimum liner materials. For next-generation 3D ICs, the suggested TSV architectures provide enhanced signal integrity and thermal-electrical performance.
