Theory of loaded scatterers
WebbThe simplest model of a scattering experiment is given by solving Schrödinger’s equation for a plane wave impinging on a localized potential. A potential V(r) might represent what a fast electron encounters on striking an atom, or an alpha particle a nucleus. WebbA general theory for analyzing scattering from loaded scatterers is available, and has been applied to small scatterers suitable for electromagnetic field measurements. The theory …

Webbför 2 dagar sedan · First, a time-of-flight based weighted function is designed, which can be calculated according to the time-of-flight of potential scatterers and scattering signals. Then, the Hausdorff distance between the reference signal and the damage signal is implemented as damage influencing factor to characterize the impact of the damage on … WebbRather than developing and presenting a formal theoretical foundation of electromagnetic theory, this book instead focuses on various aspects of EM radiation from a variety of perspectives. The goal is to provide the reader with computational tools for determining quantitatively why and where radiation is emitted by antennas and scatterers.
Webb1 apr. 2024 · Characteristic Modes Analysis (CMA) is a widely used method with recent progress in multi-antenna systems. We employ this method to characterize the mutual coupling phenomenon between two SKALA4.1 antennas, the low-frequency array elements of the future radiotelescope Square Kilometer Array (SKA-Low). The CMA accuracy is …
