Abstract
In this paper, we follow the Test-Driven Development (TDD) paradigm in the development
of an in-house code to allow for the finite element analysis of finite periodic type electromagnetic
structures (e.g., antenna arrays, metamaterials, and several relevant electromagnetic problems). We
use unit and integration tests, system tests (using the Method of Manufactured Solutions—MMS),
and application tests (smoke, performance, and validation tests) to increase the reliability of the code
and to shorten its development cycle. We apply substructuring techniques based on the definition of a
unit cell to benefit from the repeatability of the problem and speed up the computations. Specifically,
we propose an approach to model the problem using only one type of Schur complement which has
advantages concerning other substructuring techniques.
