## Abstract The objective of the present study is to show that the numerical instability characterized by checkerboard patterns can be completely controlled when nonβconforming fourβnode finite elements are employed. Since the convergence of the nonβconforming finite element is independent of the L
lemma Trigonometric Finite Wave Elements a b s t r a c t Trigonometric Finite Wave Elements (TFWE) are finite elements for solving problems in computational optics. The solution of those problems consist of highly oscillatory waves. TFWE are designed for obtaining optimal approximation properties fo
