Abstract
We compared electromagnetic(EM) wave absorption properties between Alnico magnet (A) and (B) with different magnetic properties. Also, we investigated the effect of carbon, thickness of absorbers, and Alnico contents on EM wave absorption, and clarified the relation between Alnico content and central frequency.
Key words: Alnico Magnet, Electromagnetic Wave Absorption, Different Magnetic Property, Sheet Type
