Abstract Optically transparent metamaterial absorbers have unexceptionally encountered a great challenge in further improving optical transparency ranging from visible (Vis) to near‐infrared (NIR) and environmental applicability, due the limitations of constituent materials multilayer structures. To overcome this limitation, highly Vis‐NIR metamaterial‐window with outstanding microwave broadband absorption practical durability is proposed paper, which adopts typical sandwich structure...
Abstract Although the economy of a county that is linked to surrounding towns and rural areas constitutes multiple basic economic unit within China's national economy, it usually exhibits independent characteristics functions. Consequently, county's plays critical role in overall development country's economy. We created an evaluation index system based on entropy Technique for Order Preference by Similarity Ideal Solution (TOPSIS) carry out comprehensive across entire Beijing-Tianjin-Hebei...
Intelligent reconfigurable surface (IRS) is an innovative and promising technology to achieve intelligent wireless environment, thus, enables cost-effective energy-efficient communications. Due the broadcasting nature of signals, reflected signal in IRS-assisted communications networks might suffer from eavesdropping. Thus, it essential tackle secrecy aware problems networks. In this article, we consider aerial IRS (AIRS) assisted relay network scenario, where mounted on platform. The...
Terahertz (THz) detector has great potential for use in imaging, spectroscopy, and communications due to its fascinating interactions between radiation matter. However, current THz detection devices have limitations sensitivity, operating frequency range, bulky footprint. While recent ferroelectric-integrated graphene plasmonic show promise overcoming these limitations, they are not yet extended the range. Here, we propose a wavelength-sensitive terahertz that uses single layer integrated...
Based on the Mixed Logit model, willingness-to-pay (WTP) for waste mobile phone recycling among college students in Beijing was investigated using a discrete choice experiment method. The research results three aspects of respondents' choices and WTP. (1) Their are positively affected by information security, price, method payment method, negatively amount. (2) Respondents have highest WTP security (30.04 yuan), followed price (5.94 yuan) (4.41 lowest models (2.87 yuan). (3) Personal...
Quantization emerges as one of the most promising compression technologies for deploying efficient large models various real time application in recent years. Considering that storage and IO weights take up vast majority overhead inside a model, weight only quantization can lead to gains. However, existing schemes suffer from significant accuracy degradation at very low bits, or require some additional computational when deployed, making it difficult be applied large-scale applications...
In this paper, a partially decoding scheme, combined with the rate compatible Raptor-like low-density parity-check (LDPC) codes, is proposed to provide more robust, power saving solutions for future terrestrial broadcasting systems. Different from existing works, algorithm uses least information in codeword and stops immediately after successful. We illustrate two different scenarios under which scheme will be quite useful. Simulation results show that effective.
In this paper, we consider an Aerial Intelligent Reconfigurable Surface (AIRS) assisted wireless relay network, where IRS is implemented on the aerial platform, and artificial noise added to interrupt eavesdropping. Based proposed system setup, it formulated secrecy rate maximization problem subject total transmit power reflecting phase shift constraints. To solve problem, divide into three sub-problems, i.e., allocation, AIRS trajectory optimization, optimization. Alternately optimizing...
