An algorithm to compute the Radiation Center of an antenna based on the Spherical Wave Expansion is introduced. The method is based on the angular momentum vector that is uniquely defined for any antenna far field pattern. The radiation center is defined as the phase reference point where the angular momentum is minimized and corresponds to minimizing the phase variations in the antenna far field
There are interesting links between older viewing aids like the 1800th Century Claude Glass and recent photographic consumer products like the iPhone application Instagram and the spread of HDR (High Dynamic Range) photography. I will examine these links by juxtaposing them to some issues raised by landscape- and environmental art, as well as theoretical discussions of mediation and landscape. The

Purpose The purpose is to explore if a potential gap exists between information sharing as recommended in academic literature and the information actually shared among companies and their supply chain partners. Design/methodology/approach The paper is based on an extensive literature review to structure the terminology for information sharing in supply chains and an in-depth interview study to ex
A method for dispersion-flattening in double-clad single-mode optical fibers is presented. The chromatic dispersion over the wavelength range [1.25 µm, 1.60 µm] is minimized for a w-fiber and also for a triangular-index fiber with a depressed inner cladding. The constraint that the first higher order mode should appear exactly at 1.25 µm is imposed. The full vector solution of Maxwell’s equations
