Hon Tat Hui Revision of Maxwell’s Equations NUS/ECE EE4101 2 Revision of Maxwell’s Equations 1.1 Helmholtz’s Theorem A vector field (vector function) is uniquely determined if its divergence and curl are specified everywhere and its boundary conditions are known. 1 Introduction 1.2 Maxwell’s equations state the divergences and curls of the electric and magnetic fields. When appropriate boundary conditions are also known, the electric and magnetic fields are uniquely determined from Maxwell’s equations.
