WebThe far field projections are a post-processing step to calculate the electromagnetic fields at points in space that lie far away from a structure that generates light. A typical far field projection samples the fields near the radiating structure and decomposes them into spherical or cylindrical waves. This decomposition is then used to ... WebThe cylindrical specimens are mostly field cured in insulated boxes such as a cooler or under burlap/insulation near the concrete item. In contrast, beams are mostly field cured in a damp sandpit or under burlap/insulation near the concrete item.
