the effect of external magnetic and electric fields, in the range of electroporation and magnetoporation, on lucifer yellow (ly) fluorescence in the absence of cells is studied. electric-field-induced quenching and magnetic field-induced increase are observed for fluorescence intensity of ly. regard to the fact that the variation of field-induced fluorescence, even in the absence of cells, can ...

In this paper we investigate the electrostriction effect on the whispering gallery modes (WGM) of polymeric microspheres and the feasibility of a WGM-based microsensor for electric field measurement. The electrostriction is the elastic deformation (strain) of a dielectric material under the force exerted by an electrostatic field. The deformation is accompanied by mechanical stress which pertur...

A miniaturized 2.4 GHz re-entrant cavity has been designed, manufactured and tested as a sensor for microfluidic compositional analysis. It has been fully evaluated experimentally with water and common solvents, namely methanol, ethanol, and chloroform, with excellent agreement with the expected behaviour predicted by the Debye model. The sensor's performance has also been assessed for analysis...

where E is the longitudinal electric field and Ex,y and By,x are the transverse electric and magnetic fields excited by the beam. Coupling impedances can be determined through bench measurement [1], analytically [2] or numerically by solving a discretized form of Maxwell’s equations [3]. This work focuses on finding suitable methods for the numerical calculation of coupling impedances for the r...
