Shielding of Electronic Systems against Transient Electromagnetic Interferences

Reliability of the GSM-R Communication System against Railway Electromagnetic Interferences

In this article, we study the reliability of the GSM-R system against the electromagnetic (EM) disturbances present in its railway operating environment. We thus first present the results of electromagnetic environment characterization campaigns on board moving trains in EM conditions representative of those met during a train journey. Then, we describe a new experimental protocol that has been...

Electromagnetic interference in electronic circuits and systems

This thesis examines the effects of electromagnetic interference (EMI) and coupling in circuits and systems. The coupling phenomenon is investigated in nonuniform transmission lines and adjacent via structures in microelectronic circuits. Radiation from metallic enclosures with apertures and lined with resistive materials is analyzed. Electromagnetic interference on a larger scale is studied in...

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...

PolyCond: 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...
