In this chapter, an overview of the application of this method to the analysis of rectangular waveguides containing isotropic chiral media is presented. In fact, two modifications dealing to the starting field expansions of the procedure: E and H or E and B are described. It is shown that the selection of E and B as primary fields, despite of requiring more analytical and computing work, is the optimal procedure of the coupled mode method for analyzing this kind of structure, because the solution fulfills the satisfaction of the boundary conditions over the perfect electric conductor walls and, as a result, delivers more accurate results.}, organization = {This work is part of the R + D + i Project PGC2018-098350-B-C22 funded by MCIN/AEI/ 10.13039/501100011033/ and by ERDF “A way to make Europe.”}, publisher = {Springer}, publisher = {Adventures in contemporary electromagnetic theory, 2023, 169-193}, title = {Electromagnetic wave propagation inside rectangular chirowaveguides using the coupled mode method}, author = {Gómez Gómez, Álvaro and Fernández Fernández, Óscar and Molina Cuberos, Gregorio José}, }
