Interferometric Sounding Using a Metamaterial-Based Compressive Reflector Antenna

Metamaterial Based Multiple Frequency Antenna

Antennas that are electrically small, efficient and have significant bandwidth would fill many needs of new generation communications systems if antenna engineers could reconcile these usually contradictory requirements. The introduction of the so-called metamaterials (MTMs), artificial materials which have engineered electromagnetic responses that are not readily available in nature, has provi...

Interferometric ISAR Imaging Based on Compressive Sensing

Inverse Synthetic Aperture Radar (ISAR) images are often used for target classification and recognition applications. However, conventional 2D images do not provide the height information about the scattering centers. In this paper, an interferometric ISAR imaging method based on compressive sensing (CS) is proposed that is able to estimate the scatterering centres heights. The interferometric ...

Analysis of Metamaterial Based Microstrip Array Antenna

On the design of a reflector antenna

We consider the problem of recovering a reflecting surface such that for a given point source of light the directions of the reflected rays cover a prescribed region of a far field sphere and the density of the distribution of the reflected rays is a function prescribed in advance, where the aperture of the incident ray cone is also prescribed in advance. Mathematically this problem requires on...
