The measurement setup was modeled using finite element method, while the fiber distribution is taken into account by an inhomogeneous anisotropic conductivity tensor. The study revealed a trade-off relation between the size of the ECT coil and the maximal dynamic range of the ECT signal, which contributes to the understanding of the connection between the fiber arrangement and the ECT signal and provides an opportunity for optimal ECT coil design. © 2024-IOS Press.

	abstract = {One of the significant challenges for satellite communications is to serve the ever-increasing demand for the use of finite resources. One option is to increase channel utilization, i.e., to transmit as much data as possible in a given frequency range. Since the channel is highly variable, primarily due to the ionosphere and troposphere, this goal can only be achieved by adaptively varying modulation and coding schemes. Most procedures and algorithms estimate the channel characteristics and descriptive quantities (e.g., signal-to-noise ratio). Ultimately, these procedures solve a regression problem. The resulting quantity is used as the basis for a decision process. Since valuation can also be subject to error, the decision mechanisms based on it must compensate and mitigate this error. The main element of the current research is to combine these two steps and solve them together using deep neural networks. The theoretical advantages of the method include that a better result can be achieved by having a joint estimation and decision process with a standard algorithm and cost function. The theoretical approach was tested with an actual protocol – Digital Video Broadcasting - Satellite - Second Generation – where we observed a significant improvement in channel utilization on previously recorded Alphasat satellite data. © (2024), (Czech Technical University in Prague).

The first one is based on the curl of the equilibrium equation, but it fails since it does not take account of the component of the current density parallel to the magnetic flux density and does not include the pressure as a variable. Two new formulations are introduced which remedy these shortcomings. One of them turns out to be too ill-conditioned to be used. Finally, a novel approach based on a current vector potential to represent the current density is shown to be stable and is validated by showing that it converges to the solution obtained by a previously authenticated 2D method for an axisymmetric problem.

	abstract = {Metasurface (MTS)-based reconfigurable intelligent surfaces (RISs) are able to actively control the reflection and refraction patterns on a surface to create a programmable and reconfigurable wireless propagation environment. A fast electric field integral equation (EFIE) formulation is developed here to model MTS-field interactions for RISs. The novelty of the formulation is that it utilizes characteristic basis functions (CBFs) designed specifically for approximating surface current densities on MTSs, thereby significantly reducing the necessary number of unknowns and decreasing the solution time compared with employing the standard Method of Moments technique with Rao-Wilton-Glisson (RWG) surface basis functions. In this work, we validate the novel numerical technique and demonstrate the substantial improvement in numerical performance utilizing a 2-D illustrative structure.},

	abstract = {In this article, we propose a method to provide a wideband 3-D model of a toroidal-shaped common mode choke (CMC) and extract the complex permeability curves of the toroid core. The overlapping turns of the CMC's coils are treated by equidistant turns and external capacitors, while the complex, frequency-dependent permeability is modeled by a second-order general dispersion model. Obtaining the optimal capacitance values and dispersion model parameters is addressed as an inverse problem that leads to a minimization of the misfit between the simulated-with 3-D finite element (FE) method-and measured transfer scattering parameter curves of the CMC. The computational cost is reduced by a polynomial chaos kriging (PCK) surrogate model (SM) that is built using a small sampling design and is subsequently used as a low-cost substitute for the FE model to support the great number of model evaluations that the inverse problem implies.},

Through numerical examples, we illustrate the scope and convergence of the method. Applications of interest include circularly polarized patterns, since the algorithm can handle the rotation as well as translation of the antenna elements, in addition to broadband systems, as the method is capable of characterizing the performance of arrays at multiple frequencies. © 2023 IEEE.},
