Caracterización electromagnética de materiales mediante medidas de alta precisión en espacio libre

Abstract

Aerospace or automotive industries employ novel composite or 3D printed materials in their manufacturing processes to improve performance and reduce costs. Obtaining the electromagnetic (EM) characterisation of these materials or a combination of them is essential to ensure safety and EM compatibility. In this paper, the development of a test bench with polyrod antennas for measurements in free space is presented. A complete design is described, from simulation analysis to validation measurements. The aim is to achieve flexible measurements that permit the electromagnetic characterization of very diverse samples and materials, and high accuracy measurements that allow to know the exact behavior of these materials.
