One of the characteristic features of the electromagnetic fields radiated by lightning is the far-field inversion of polarity with a zero-crossing occurring in the tens of microseconds range. This feature has been used in several studies to test the abilit ...
Mode-selective surface-enhanced Raman spectroscopy (SERS) is demonstrated using plasmonic dipole antennas fabricated with electron beam lithography. An similar to 10x change of the relative enhancement between two different Raman modes is observed when the ...
The electromagnetic effects of a High Altitude EMP have been a threat for communications and installations, largely studied and documented between 1960 and 1990. During the last decade of the 20(th) century, a new kind of electromagnetic field representing ...

With the deregulation of the electricity and telecommunications markets, a great deal of new operators providing some innovative services have appeared. In the telecommunications' field, the promise of broadband Internet access with easy installation proce ...
Integral equation (IE) formulations.solved by the Method of Moments (MoM) have been used successfully to address a vast variety of electromagnetic problems. Printed circuits embedded partially or totally in laterally bounded multilayered media,such as micr ...
Human HaCaT cells, exposed for 24 h to a 1 mT (rms) 50 Hz sinusoidal magnetic field in a temperature-regulated solenoid, suffer detectable changes in their biochemical properties and shapes. By using infrared wavelength-selective scanning near-field optica ...
The aim of this thesis is the study of the simulation of electrically large structures and the application of the results to automotive Electromagnetic Compatibility (EMC). The theoretical and experimental work carried out has led to the development of com ...
A technique for the accurate computation of the electromagnetic fields radiated by a charged particle moving within a parallel-plate waveguide is presented. Based on a transformation of the time-varying current density of the particle into a time-harmonic ...

The performance of multiband-OFDM UWB systems is analyzed using the S-V indoor channel model. Based on the analysis, two methods are proposed to improve the reliable transmission range of UWB devices by exploiting the rich spectral and spatial diversity av ...
