Electromagnetic Characterization of Composite Materials and Microwave Absorbing Modeling
This book chapter is based on the experimental activities conducted mainly at Sapienza University of Rome: Astronautic, Electric and Energetic Engineering Department in collaboration with University of Maryland, Institute for Research in Electronics and Applied Physics (IREAP). A branch of scientific research about composite materials is focused on electromagnetic characterization and subsequen...
متن کاملAbsorbing boundary conditions for electromagnetic wave propagation
In this paper, the theoretical perfectly absorbing boundary condition on the boundary of a half{space domain is developed for the Maxwell system by considering the system in whole instead of considering each component of the electromagnetic elds individually. This boundary condition allows any wave motion generated within the domain to pass through the boundary of the domain without generating ...
متن کاملCasimir Interaction between Absorbing and Meta Materials
The Casimir force is one of the most accessible experimental consequences of vacuum fluctuations in the macroscopic world. It is the most significant force between neutral, non-magnetic objects at distances on the micrometer scale and below. For many experiments searching for novel short-range forces predicted by unification models, theoretical calculations of the Casimir force are crucial and ...
متن کاملElectromagnetic and microwave-absorbing properties of magnetic nickel ferrite nanocrystals.
The electromagnetic and microwave absorbing properties of nickel ferrite nanocrystals were investigated for the first time. There were two frequencies corresponding to the maximum reflection loss in a wide thickness range from 3.0 to 5.0 mm, which may be bought by the nanosize effect and the good crystallization of the nanocrystals.
متن کاملElectromagnetic Wave Absorbing Properties of Amorphous Carbon Nanotubes
Amorphous carbon nanotubes (ACNTs) with diameters in the range of 7-50 nm were used as absorber materials for electromagnetic waves. The electromagnetic wave absorbing composite films were prepared by a dip-coating method using a uniform mixture of rare earth lanthanum nitrate doped ACNTs and polyvinyl chloride (PVC). The microstructures of ACNTs and ACNT/PVC composites were characterized using...
