A model of a sample with a periodic or non-periodic pattern of conductive and transparent materials is produced based on the effect that the pattern has on TE polarized incident light. The model of the pattern may include a uniform film of the transparent material and an underlying uniform film of the...http://www.google.de/patents/US8126694?utm_source=gb-gplus-sharePatent US8126694 - Modeling conductive patterns using an effective model
