Conventional Hall devices are widely employed to measure magnetic fields produced by millimetre sized (or larger) current-caring conductors or permanent magnets with a standard active area of about (100 um)^2. Micro-Hall sensors have recently emerged as a ...
The coupling and transmission of transverse and longitudinal fields into apertureless microfabricated near-field optical probes is investigated. Two kinds of probes with different metal coating roughness are considered. Transverse and longitudinal field di ...
The propagation of the electromagnetic field in fully coated near field optical probes was analyzed. It was proved that these structures allow nonzero modal emission of the electromagnetic field through a 60-nm thick metallic layer. It was also found that ...
We present measurements of decay amplitudes and triple-product correlations in B→K* decays based on 253fb-1 of data recorded at the Υ(4S) resonance with the Belle detector at the KEKB e+e- storage ring. The decay amplitudes for the three different helicity ...
The paper is a contribution to the studies of factors that can affect electric (E) and magnetic (H) fields associated with lightning return strokes to tall structure. Herein, the influence of lightning channel inclination upon vertical E-field and azimutha ...
In this thesis work we avail ourselves of optical interferometric techniques for the study of the optical properties of nano-structured materials. As a first step, we set up a multiple heterodyne scanning probe optical microscope (MH-SPOM). This apparatus ...

A study of the optical properties of microfabricated, fully-metal-coated quartz probes collecting longitudinal and transverse optical fields is presented. The measurements are performed by raster scanning the focal plane of an objective, focusing azimuthal ...
In this thesis various phenomena that appear if light interacts with objects having a size comparable to the wavelength are experimentally and theoretically analysed. The work is concentrated on the analysis of phase singularities in electromagnetic fields ...

We discuss some of the intrinsic difficulties related to the numerical investigation of near-held optical microscopy. We show how these difficult ies can be handled within the framework of the Green's tensor technique. Investigating practical experimental ...

The main purpose of this thesis is to explore a new concept of SNOM probes. In order to produce more reliable and reproducible tips, we propose to graft a single gold particle of 60 nm diameter onto the aperture of a SNOM probe. The expected advantage of s ...
