Abstract

Composite materials consisting of micro- or nanogranules have great potential for microwave application as electromagnetic wave absorbers [1, 2]. We have studied the dynamic properties of arrays of ferromagnetic micron-sized Co particles deposited onto anodized porous alumina surface by electrodeposition. This method allows controlling of some factors to organize the metal into granule assembly with various particle shapes.
