creator Bridges, Jack E. Optimum antenna-like exciters for heating earth media which may be used to recover hydrocarbons. A high frequency power supply is connected to an exciter emplaced in the subsurface formation which radiates high frequency power. The exciters include one or more conducting cylinders which make up monopole and dipole antenna-like apparatus. Substantially uniform heating of the subsurface formation is provided thus suppressing excessive heating of edge and power input regions. The equal distribution of electric fields eliminates intense electric fields which would normally exist thus mitigating excessively heated regions and providing substantially uniform heating of the subsurface formation.
