“…Application of FIT often results with the discrete equations, identical to the ones derived with finite-difference time-domain method [31]. In [32], it presents theoretical links of abovementioned methods realised in CST package [31]. The applied boundary conditions are derived from an integral form of Maxwell's equation and differential form of grid Maxwell's equations using approach introduced in [33].…”

The aim of this study is a numerical analysis of the electric field and the specific absorption rate (SAR) distribution within a realistic 3D‐human eye model exposed to electromagnetic (EM) wave of virtual reality (VR) glasses at the frequency of third generation, long‐term evolution‐4G, and the frequency of the latest generation of mobile networks – 5G. To obtain the values of the electric field and SAR, the numerical solution of equations of EM waves propagation has been used. A new realistic 3D‐human head and human eye model has been created. The obtained results are shown for different biological tissues of the eye exposed to EM radiation from VR glasses at different frequencies. The maximum absorption of EM energy will be discussed for the following frequencies: 900 MHz, 2.6 GHz, and 28 GHz. The maximum values of electric field strength in the human eye tissue at the frequencies 28 GHz and 900 MHz are 94.43 and 137.3 V/m, respectively (higher than referent values), whereas for 2.6 GHz amounts 8.62 V/m (lower than referent limits). The obtained SAR peaks do not overcome prescribed safety values.

“…The CST Studio® 3D electromagnetic simulation software was used for modelling the electromagnetic response of these carbon-based cellular structures, using the finite integration technique (FIT) applicable for both time domain and frequency domain. FIT is a discretisation scheme for integral Maxwell's equations, where the resulting matrix equations of the discretised fields are used for numerical EM simulations (see [20] for details of calculations and simulations). The simulation of microwave and THz responses was carried out for both Kelvin-and Gibson-Ashy-type 3D structures with geometric parameters (i.e., cell and window sizes) compatible with the considered wavelengths.…”

The electromagnetic response of 3D-printed periodic carbon structures was investigated numerically and experimentally in the microwave (26-37 GHz) and terahertz (0.2-1.2 THz) frequency ranges. The reflection, transmission and absorption spectra, as well as the effects of the concentration of electromagnetic waves, were analysed and discussed. High broadband absorption was observed for the 3D-printed cellular structures based on a moderately conductive (1 -30 S•m -1 ) skeleton, whereas perfect tuneable resonant absorption could be achieved by 3D meshes made of highly conductive (1 200 -2 000 S•m -1 ) glassy carbon. We show that laser stereolithography (SLA) or fused deposition modelling (FDM) 3D-printing technique should be preferred for getting pre-defined required electromagnetic performances depending on the intended application.

“…The increasing demand of the quality of service has led to very restrictive system specifications, which are translated into more complex microwave and millimeterwave devices. In order to accomplish such designs, CAD (Computer Aided Design) tools have experienced a strong development over the last decades [3,4].…”

The analysis of the electromagnetic scattering at discontinuities between equilateral triangular waveguides is studied. The complete electromagnetic solution is derived using analytical closed form expressions for the mode spectrum of the equilateral waveguide. The mathematical formulation of the electromagnetic scattering problem is based on the quasi-analytical Mode-Matching method. This method benefits from the electromagnetic field division into symmetries as well as from the plane wave formulation presented for the expressions involved. The unification of the surface integrals used in the method thanks to the plane wave formulation is revealed, leading to expressions that are very well suited for its implementation in an electromagnetic analysis and design code. The obtained results for some cases of interest (building blocks for microwave components for communication systems) are verified using other numerical methods included in a commercial software package, showing the potential of the presented approach based on quasi-analytic expressions.
