Abstract: In this paper a simple and efficient ray-tracing model is presented to evaluate two-dimensional (2D) multilayer dielectric lenses combined with arrays. The proposed algorithm is capable of ...

Generally imaging with an RCA 2-D array is limited to its forward-looking volume region. Constructing a double-curved RCA 2-D array or applying a diverging lens over the flat RCA 2-D array, can extend ...

But the brand’s no stranger to a protractor. Designed in 1967, the Hexagonal ditches Ray-Ban’s usual curves in favor of flat crystal lenses and a stop-sign’s angles. It stands out without ...

It was well received, although it ran without subtitles. This May 3, Satyajit Ray’s cinema turns 70. The maestro, incidentally, would have turned 104 on May 2. If he were alive and still making movies ...
