Abstract

The quality of tomographic images formed from diffracting waves deteriorates due to the limitations in capturing evanescent waves. The waves carry detailed information about the body being imaged. Metamaterials are being recently used to amplify and focus evanescent waves. Here, the physical characteristics of a superlens made out of a silver metamaterial slab are studied. A description of the equations for wave propagation inside the metamaterial is shown. The dependence of the cutoff frequency of a superlens on the thickness of the slab is discussed. Suitable physical dimensions of a superlens are proposed for cross sectional imaging of objects with geometrical shapes. Simulations are done to test the validity of the proposed solution.
