Previous issue date: 2010-12-06 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Metamaterials exhibiting negative refraction have attracted a great amount of attention
in recent years mostly due to their exquisite electromagnetic properties. These materials are
artificial structures that exhibit characteristics not found in nature. It is possible to obtain a
metamaterial by combining artificial structures periodically. We investigated the unique
properties of Split Ring Resonators, High impedance Surfaces and Frequency Selective
Surfaces and composite metamaterials. We have successfully demonstrated the practical use
of these structures in antennas and circuits. We experimentally confirmed that composite
metamaterial can improve the performance of the structures considered in this thesis, at the
frequencies where electromagnetic band gap transmission takes place
