Parametrically shielding electromagnetic fields by nonlinear metamaterials.
An analytical theory is developed for parametric interactions in metamaterial multilayer structures with simultaneous nonlinear electronic and magnetic responses and with a near-zero refractive index. We demonstrate theoretically that electromagnetic fields of certain frequencies can be parametrically shielded by a nonlinear left-handed material slab, where the permittivity and permeability are...
متن کاملEffect of various parameters on electromagnetic shielding effectiveness of textile fabrics
The effect of material type, yarn count, pick density, type of mordant and layers of fabrics on the electromagnetic shielding properties of textile materials has been studied. The shielding effectiveness of the fabric is measured by estimating the insertion loss incurred to the signal when the sample is placed in the path of the signal at the frequency range 100 MHz-3 GHz inside the coaxial tra...
متن کاملDielectric properties of polypropylene fabrics with carbon plasma coatings for applications in the technique of electromagnetic field shielding
Within the current work an attempt was made to use glow discharge low temperature plasma processing to produce carbon coatings on polypropylene unwoven fabric for electromagnetic field shielding applications. Layers were obtained from the gaseous phase (propane–butane). The influence of coatings on the dielectric buffer properties of modified fabrics was investigated. The Havriliak–Negami (HN) ...
متن کاملPolyCond: electromagnetic shielding with conducting polymers
Picture this: your mobile phone is lying on your desk, close to the speaker of your computer system. A few seconds before you receive a call or SMS message on your mobile phone, the speaker makes a buzzing noise. Is this clairvoyance of the speaker? No way. Here, the wire to the speaker acts like an antenna that picks up and amplifies the signal it receives from the mobile phone network. This i...
متن کاملElectromagnetic Shielding Effectiveness Evaluation For Materials
The theory of electromagnetic shielding is based on the waves equations describing the behavior of electromagnetic field in material. The proposed approach consist in a PSpice model using transmission line model to simulate the attenuation introduced by a material characterized by the macroscopic parameters ε, μ, σ. To verify the data obtained through PSpice simulation, a wave-guide-based measu...
