Multi-beam Antenna Arrays for Base Stations in Cellular Communication Systems
… on a spherical Luneburg lens implemented with an artificial dielectric material which is approaching low frequency limitations of excessive size, weight and anisotropy is explored. In the case of Butler matrix networks, control of beamwidth and sidelobes is studied as are implementation details …

Nonlinear optical properties of nano structures
… in the range of 1-100nm are hosted in a dielectric material and are considered as a particular example of Conditional Artificial Dielectric (CAD). It has been reported that the dielectric properties of such materials will be greatly changed by light intensity. Two main paths to realize …

Novel Devices for Terahertz Wave Imaging, Wave-guiding and Sensing
… probe is proved to be able to differentiate the dielectric features as well as topographic information on the sample. Combined with the methodology of filtered back projection, we reconstructed a two-dimensional image of a gold pattern on a GaAs chip by using this tapered PPWG probe. The smallest …
