Abstract

Napravljen je kritički pregled dosadašnjih istraživanja i proučeni su problemi i pokazani efekti. Na temelju toga napravljene su brojne simulacije različitih struktura koje pokazuju efekt D-dot petlje i razni načini pobude tih struktura. Pronađena je optimalna pobuda koja najmanje „maskira“ efekte i daje najbolje rezultate.
Slično istraživanje provedeno je za D-dot žicu, samo je u simulacijama, osim idealne kontinuirane strukture, korišten već ranije razvijen model D-dot replike. Pokazani su različiti načini pobude i mjerenja posmačne struje, objašnjeni su rezultati i izneseni problemi. Predložena je potpuno nova struktura temeljena na drugačijoj izvedbi ENZ plašta koja bi se trebala ponašati kao D-dot žica te je napravljen fizički demonstracijski prototip i mjerenja..

Abstract (english)

A critical review of existing studies has been given. Also, the problems and demonstrated effects have been revised. Numerous simulations of various structures, based on existing studies, that show the D-dot loop effect, and excited with various excitations, have been made. The most of the time was spent on finding the optimal excitation, which ''masks'' the aforementioned effects the least and gives the best results.
Similar investigation has been done in the case of D-dot wire. In this investigation two different models have been used: continuous and wire-based model. Various methods of displacement current measurements have been described, with pros and cons compared and discussed. The novel structure, which is expected to have a D-dot wire behaviour, has been proposed and prototype has been contructed and measured.
