Quasi periodicity in moire patterns and a numerical approximation method of dual weaves

摘要

This work describes a method to compute the periodicity and the relative hole area of a dual weave arrangement where the weaves are rotated relative to each other. Due to the discovery of 2D quasi periodicity in these dual weaves, a method developed to approximate the macroscopic behaviour of the dual weave is introduced. These methods are useful when designing dual weave reflector antenna surfaces for satellite communication applications.
