The FDTD Simulating the Attenuation of a Plan Electromagnetic Wave Crossing of a Radome in the Weather Radar
This article presents the results of simulations in plan electromagnetic waves (EMW) horizontally polarized propagate through the radome of protection in a Weather) Radar antenna, using the method of Finite Difference in Time Domain (FDTD). Creating a limited computerized space with focus in the best answers in operational equipment frequency at 2.8GHz. Simulations the same plan EMW at open space (Air); crosses a radome composed of Goretex®; crosses a radome covered by a thin water rain layer plate, and also a crosses a junction of plates of radome containing one stainless steel screw used for joint the plates. Comparing the results for each one simulations and knowing the attenuation of radiated (EMW) by the Weather Radar.
