Recently, the development of electronic and electric devices has caused an increase in the level of electromagnetic radiation; therefore, the demand for protection against this danger has increased. There are many ways how to ensure the protection of device against electromagnetic interference; however, this paper is devoted just one of the ways, the shielding. The paper is focused on calculati...

Electromagnetic interference can be easily coupled into metallic shielding enclosure that is penetrated with a conducting wire, which having a harmful effect on electrical and electronic devices. To sudy the characteristics, Finite Difference Time Domain (FDTD) is applied in both frequency and time domain for modeling the coupling of an incident electromagnetic pulse (EMP) with a conducting wir...

The transmission line matrix time domain (TLM-TD) method is used to simulate the electromagnetic pulse (EMP) coupled inside a shielding box with an aperture. Simulations for different electromagnetic pulses regarding to different rise time and fall time have been performed. The results for shielding effectiveness of these different excitations have been presented. A simple method that uses an e...

There is increasing interest in electromagnetic interference (EMI) shielding due to the serious electromagnetic environment pollution caused by the continuously increased use of the electrical products and electronic devices. Electrical conductivity and EMI shielding effectiveness (SE) of composite materials made from silicone rubber with carbon powder and ferrite powder have been studied in mi...

In-situ homogeneous dispersion of noble metals in three-dimensional graphene sheets is a key tactic for producing macroscopic architecture, which is desirable for practical applications, such as electromagnetic interference shielding and catalyst. We report a one-step greener approach for developing porous architecture of 3D-graphene/noble metal (Pt and Ag) nanocomposite monoliths. The resultin...
