Návrh planárních anténních struktur z metamateriálů
Javora, Petr ; Polívka, Milan (oponent) ; Raida, Zbyněk (vedoucí práce)
V této práci jsou studovány základní principy metamateriálů, které vykazují v mikrovlnné technice nezvyklé vlastnosti jako je záporná permitivita či permeabilita. Jsou zde popsány typy a vlastnosti antén tvořených metamateriály.
Modeling metamaterial microwave resonators
Zvolenský, Tomáš ; Kovács, Peter (oponent) ; Raida, Zbyněk (vedoucí práce)
The project is aimed to modeling microwave resonators from metamaterial (materials with negative refraction index). First, basics of metamaterials are explained, their creation is described, and their properties essential to the design of microwave resonators are discussed. Second, a metamaterial planar resonator is designed. For this purpose, functions for computing the layout dimensions were programmed. The designed structures were simulated in Zeland IE3D. Simulated structures were optimized to reach desired resonant frequencies. The first resonator consisted from a single elementary cell, and the second one from two cells tuned to different frequencies. Resonators were fabricated, and their properties were experimentally verified.
