Originální abstrakt

It is possible to manipulate electromagnetic field by means of dielectric materials. Electromagnetic field will be affected due to values of dielectric constant er and permeability ur. Viktor Veselago has defined theoreticaly the usage of material with negative parameters (metamaterial) as an electromagnetic lens. If we put metamaterial between transceiver and receiver, we can see an increase in detected energy. It appears that the metamaterial behaves like an electromagnetic lens. The subject of this work is construction and optimization of electromagnetic lens for mid-field MR tomograph. Principles of lens construction are in [1-3]. Paper contains analytic calculations of basic design of the lens and numerical calculations of the optimized lens.
