Abstract

A non-conventional shielding solution, with useful applications in civil engineering, is presented. The composite based on ferrimagnetic garnets from chemical plant residuals is analysed in a room-shaped geometry and the influence of some parameters (frequency, thickness of the shield layer, applied magnetic field, configuration of the room walls) is studied. The experimental and numerical data show the effectiveness of this ecological and low-cost shielding solution..
