We measure the extremely long distances between things in space by light years. A light year is the distance that light travels in one Earth year. Light travels at about 300,000 kilometres per second.

We propose a silicon photonic filter using an elliptical micro-ring, and describe in detail of the simulation studies conducted on minimizing the bent radius and maximizing the free spectral range ...

This work proposes a leaky-wave antenna based on a series-fed patch array with semi-elliptical arms for X-band radar applications. The antenna uses series-fed patch unit-cells with elliptical arms as ...
