Angle-dependent SIBC model of metamaterial in FDTD method

, 2022
To control the diffraction of a target illuminated by a RADAR wave, one technique is to consider metamaterials. Simulating their behaviour can be complex especially when they are applied as thin heterogeneous layers on the surface of the target. This can be achieved, by first determining an angle-dependent surface impedance model, that is after ...

New aspects on the determination of soil‐specific respiration quotients of arable soils for the application in the barometric process separation technique

Journal of Plant Nutrition and Soil Science, Volume 187, Issue 3, Page 388-400, June 2024.
Abstract Background The respiratory quotient, that is, the CO2–O2‐exchange ratio during aerobic heterotrophic soil respiration, (RQAHR) is one of the key variables of the barometric process separation (BaPS) technique. For reliable application, the BaPS method requires the adjustment of RQAHR to soil‐specific substrate conditions.

Spatial Resolution Requirements for FDTD Modeling of Geoelectric Fields

Journal of Geophysical Research: Space Physics, Volume 129, Issue 6, June 2024.
Abstract To ensure the robustness of both civilian and military infrastructure, it is important to protect electric power grids, smart grids, and other electrotechnologies from known and possibly as‐of‐yet unknown space weather hazards. Space weather can generate intense geoelectric fields at the surface of the Earth, as well as large voltage gradients

New approximation method for high order impedance boundary condition with surface integral equations for the scattering problem

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 37, Issue 3, May/June 2024.
Abstract In this paper, we propose a new method to approximate operators resulted from solving the scattering Problem in electromagnetism by dielectrically coated conducting bodies, using integral equations and high order impedance boundary condition. We introduce the variational Problem and we prove its well‐posedness.

Genesis and Classification of Nitisols from Volcano-Sedimentary Lithology in Northeastern Brazil

Revista Brasileira de Ciência do Solo, 2019
On the southern coast of Pernambuco State (PE), Brazil, lithotypes of the Cabo Basin (volcanic and sedimentary rocks), in association with the relief, allow the determination of the dynamics of the formation of Nitossolos Háplicos (Nitisols), including ...
