Bahl and Tripathi's work on waveguide modes

Bahl and Tripathi studied how electromagnetic waves propagate within waveguides—hollow structures that direct signals like microwaves or light. They analyzed the different patterns, or modes, that these waves can form inside the guide. Their work helps us understand how to design waveguides more effectively for efficient signal transmission, minimizing losses and optimizing performance. By mathematically characterizing these modes, their research provides insights crucial for advancements in telecommunications, radar systems, and other technologies relying on controlled wave propagation.
