Reverse operation self-consistent evaluation for curved domain interfaces in non-conformal domain decomposition methods

This paper introduces a Transmission Condition (TC) featuring Reverse Operation Self-consistent Evaluation (R.O.S.E.) in the framework of Non-overlapping non-conformal Domain Decomposition Methods (DDM). In R.O.S.E., the sparsity pattern of transmission matrix is first analyzed based on the two non-conformal discretization (triangulations) on the domain interfaces. Thereafter, the matrix entries are recovered from known self-consistent samples. R.O.S.E. provides great flexibility and advantage for modeling antenna arrays, metamaterials, frequency selective surfaces on doubly curved platforms.
