Figure 1: Experimental geometry and microscopy of screen and test pattern. To determine an effective working limit for the distance separating the sample and the exit screen we performed numerical ...

The behavior of a negative refraction photonic crystal slab irradiated with out-of-plane incident beam is an unexplored subject. In such an experimental configuration, guided mode resonance appears in ...

Abstract: We consider the Comptonization of the photons that make up the relativistically blurred reflection that is commonly detected from the accretion discs of active galactic nuclei by the coronae ...

Abstract: The author looks at the geometry of the classic law of mirror reflection. This law tells us that the angle of incidence equals the angle of reflection. It turns out that this little ...
