Unified Approach to Acoustic and Electromagnetic Field Theories Based on Control Engineering Methods
Abstract
In this paper, we propose a unified approach to acoustic and electromagnetic field theories which employs control
engineering methods for their analysis and modelling. Both theories can be derived from the wave equation using factorisation
and subsequently represented as a system with a feedback loop in control engineering. This allows for the formulation of properties and solutions useful for further analysis. Moreover, it provides a justification and explanation of similarities between acoustics and electromagnetism. Hopefully, our unified approach to acoustic and electromagnetic field theories carries implications for the foundational understanding of both theories as well as their practical applications.
