Abstract
An imaging device arranged to image near field as well as far field components from an object comprises a stack of layers 8 spaced apart from each other, the layers having a negative real part of electrical permittivity or magnetic permeability in a direction normal to the layers, and being constructed from microstructured material comprising an array of elements spaced apart from each other by a distance less than the wavelength of radiation to be imaged. The layers may be spaced 9 by medium of positive real part of electrical permittivity or magnetic permeability, both the layer and the spacing being isotropic. In an alternative embodiment, the layers are in pairs in which the component of electrical permittivity or magnetic permeability in a direction normal to the layers is alternately negative and positive, while the electrical permittivity or magnetic permeability in a transverse direction is positive or negative, respectively. In an alternative embodiment, the magnitude of the component of the electrical permittivity or magnetic permeability is very large in a direction normal to the incident face. The device operates in the microwave and millimetre range.
