Abstract: In this talk, firstly, I am going to explain our recent predictions of very interesting electromagnetic phenomena such as efficient radiation from small antennas, perfect absorption, enhanced transmission, negative refraction and coupled mode hybridization that are observed by using various designs of artificial structures. Secondly, I will describe our ongoing studies on imaging chain approach for earth observation satellites, which allows us to estimate satellite image quality, before the systems are physically built and operational. The adventure of sun light starts with the fusion reaction in the core of the sun. It exits from the sun’s surface, transmits through earth’s atmosphere and is being reflected from several targets located on earth’s surface. After transmission through the atmosphere one more time, it reaches the spaceborne optical systems (satellite cameras). I will provide details of key operations that identify the satellite image quality such as camera design, radiometric chain, spatial chain, and image processing, and describe image quality quantification methods.
