Design of multiple-layer microwave absorbing structure based on rice husk and carbon nanotubes

This paper presents a multiple-layered microwave absorber using rice husk and carbon nanotube composite. The dielectric properties of each layer composite were measured and analysed. The different layer of microwave absorber enables to control the microwave absorption performance. The microwave abso...
