Electromagnetic Waves

8.1 INTRODUCTION

Space variations of electric and magnetic field components are associated time variations of magnetic and electric field components, respectively. This interdependence gives rise to “ electromagnetic wave propagation”.

8.2 WAVE EQUATIONS FOR WAVES TRAVELLING IN SPACE

General wave equations using Maxwell’s equations are derived. In electromagnetics (EM), the basic and fundamental relations that need to be satisfied are
