Efficient and Accurate Prediction of Cosite Isolation on Large Platforms - Wiley Science and Engineering Content Hub

[pdf_cover] Download this complimentary White Paper today! This White Paper shows engineers and researchers how to predict, by simulation, the coupling between antennas mounted on electrically large platforms such as an airliner — and how to keep the results accurate even when the coupling is as low as -100 dB. What you will learn about:   Why platform size and coupling strength are two separate problems, and why the antenna pairs hidden from each other are the demanding case. How higher-order basis functions allow patches up to 2λ in size, reducing the number of unknowns compared with conventional low-order triangular meshing — and why the cubic cost of a direct solve makes every unknown you avoid pay back many times over. Why every numerical model of a closed metal platform behaves like a cavity, and how the spurious fields trapped inside it, not the platform itself, spoil low-level results. How to treat the reference frequency as a convergence test, so you can see when a coupling result has settled instead of assuming it. How absorbing material and air-filled ‘bubbles’ suppress spurious fields, allowing accurate low-level coupling results with fewer unknowns. Click "LOOK INSIDE" to Download Now.
