We explicitly prove that the transfer matrix of a finite layered PT -symmetric system of fix length L consisting of N units of the potential system ‘+iV ’ and ‘−iV ’ of equal thickness becomes a unit matrix in the limit N → ∞. This result is true for waves of arbitrary wave vector k. This shows that in this limit, the transmission coefficient is always unity while the reflection amplitude is zero for all waves traversing this length L. Therefore, a free space of finite length L can be…

TLDR
A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
