It is shown that anomalous boundary conditions at the surface of a negative‐refractive‐index
metamaterial planar lens severely diminishes the resolution of the lens when its relative …

An imaging system comprising a planar negative-refractive-index lens and a pair of small
loop antennas is described. The two loops antennas are fixed on one side of the lens, and …

It is shown by simulation that a sharp image of a lossy object with an abrupt change in
permittivity can be obtained using a negative-refractive-index (NRI) lens at 3 GHz. The …

Two modelling methods of an experimental 3 GHz negative-refractive-index lens comprising
an array of dielectric resonators and metal strips are compared. One model approach …

An experimental 5-pixel microwave imaging system, operating at 3 GHz, is demonstrated. It
employs a planar negative-refractive index lens. A single pixel comprises a pair of small …

Deconvolution of images captured with an experimental 3 GHz negative-refractive-index
lens imaging system can reveal 0.1 wavelength features. The spatial spectral transfer …

A dual probe system has been developed for conducting experiments at frequencies near 3
GHz. The system contains a pair of square loops and each of them is loaded by a cubic …

A new method for additive manufacturing of human torso phantom is being developed to
support the study of pneumothorax using a microwave imaging system. Conductive PLA has …

An experimental negative-refractive-index lens based system operating around 3 GHz is
used to image muscle and bone samples. This system can resolve features at least as small …
