This paper presents a low-profile, dual-stopband active frequency selective surface (AFSS) with an ultra-wide band ratio (BR) to overcome the limited tuning range and suboptimal profile of current designs. The proposed design consists of a periodic pattern printed on the top of a thin substrate and a bias network on the bottom, with varactor diodes symmetrically mounted on the top metal layer. Based on the equivalent circuit model, the mechanism of wideband tuning is analyzed theoretically.

Numerical simulations are used to assess the efficiency of floor heating, ceiling heating, and plane radiator heating in a selected family house room under winter conditions in the Central European climate zone. COMSOL Multiphysics software was used for computer simulations. The output data were subsequently processed and analyzed using MATLAB software. Results indicate that floor and ceiling heating systems achieve higher and more rapid temperature increases compared to plane radiators.

An improved coupled mode theory, grounded in the field matching technique, has been devised and validated for photonic devices with gradually varying structures, such as tapers. This novel approach addresses a limitation of traditional coupled mode theory, which approximates varying structures by dividing them into several uniform sections with different waveguide widths. This segmentation often leads to unphysical field reflections at the interfaces between adjacent sections, impacting both power propagation and reflection coefficients of the devices.

This dataset describes the measured or calculated values of most components shown in the Dataset Image. These components were used to accurately model a Pierce oscillator circuit for RT operation. Each bond wire (W1, W2, etc.) is represented by a series resistance and inductance placed parallel with a capacitor, all calculated based upon the length of the wire. Each inconel and standard coaxial cable (CI1-2 and CO1-2) is represented with the same three components.

A crucial requirement for effective human-AI teaming is the ability to form mutually compatible mental models that help humans discern when the AI can be relied upon and how to best complement each other. To understand the impact of having this mutual understanding, we conducted an experiment where participants (N=125), tasked as disaster relief planners, were assisted by an AI agent that recommends optimal allocation of a resource based on several information sources. The interaction effects of mental models between the human and the AI were studied.
