A temporal phase-unwrapping algorithm has been developed for the analysis of dynamic interference patterns generated with interference-contrast microscopy in micromachined picoliter vials. These vials are etched in silicon dioxide, have a typical depth of 6 mum, and are filled with a liquid sample. In this kind of microscopy, fringe patterns are observed at the air-liquid interface. These fring...

By numerically calculating the relevant electromagnetic fields and charge current densities, we show how local charges and currents near subwavelength structures govern light transmission through subwavelength apertures in a real metal film. The illumination of a single aperture generates surface waves; and in the case of slits, generates them with high efficiency and with a phase close to -π w...

Our modern society depends on the functioning and interplay of a wealth of infrastructures. Practically all of these infrastructures are in some form or another, dependent on electrical and electronic systems. The majority of modern infrastructure is dependent on electric power and controlled by Supervisory Control and Data Acquisition (SCADA) systems. Electronic systems are sensitive to electr...

The research report presents the chip-scale solutions for THz spectroscopy applications. On the transmitter side, the architecture achieves dynamic waveform shaping of THz periodic waveform in free space by allowing interference of radiated electromagnetic-fields with rich harmonic components and proper delays at far field. On the receiver side, the electromagnetic interface between the on-chip...

We report an experimental method to determine the generalized Stokes parameters for a pair of points in the cross section of an electromagnetic beam, e.g., an expanded laser beam, with the help of a Young's interferometer and a set of polarizers and quarter-wave plates. The method is investigated theoretically using the electromagnetic spectral interference law. The generalized Stokes parameter...

An integral equation is formulated to describe electromagnetic wave transmission through a subwavelength nano-hole in a thin plasmonic sheet in terms of the dyadic Green's function for the associated Helmholtz problem. Taking the subwavelength radius of the nano-hole to be the smallest length of the system, we have obtained an exact solution of the integral equation for the dyadic Green's funct...

The EMI filters are usually used for suppression of electromagnetic conducted interference of range 9 kHz-30 MHz. The efficiency of electromagnetic interference filter is described by attenuation characteristics. The value of attenuation of EMI filter depends on main parameters of filter’s elements and its parasitic parameters. Therefore the high frequency model of electromagnetic interference ...
