Selection of microwave absorber materials for RF applications

In RF applications, the correct selection of microwave absorbers is crucial to minimize unwanted reflections, resonances, and electromagnetic interference. Materials are often selected based on frequency range, but attenuation coefficient, angle of incidence, polarization, thermal behavior, and environmental conditions also influence performance. Understanding these parameters and the trade-offs between them is essential for designing reliable and efficient systems. This presentation provides a practical framework for engineers to evaluate and select absorber materials.
