\section{Introduction}  In a discussion of Resonance Cones one wants to answer the question of what What  happens to a plasma when there is an oscillating point charge [1]. charge? In order to solve this one needs to solve Gaus's law with the dielecttric constant of the plasma. This gives in an equation for electric field and resonance cones are described by the radial component of the electric field. What is discovered is that the electric field forms a cone with cylindrical geometry described by it's resonance cone angle. Ray Fischer in his thesis paper showed by plotting cone angle with wave frequency for different densities that resonance cones aren't quite like dispersion relations but rather an intereference pattern [1].The wave numbers for different frequencies interefere the sum to give a large electric field at the resonance cone angle and no electric field at any other positions.
