Some group of students from Prof. Dowell classes, decided to improve their CV by means of direct electromagnetic action on professor's head. Under the cunning supervision of
Dr.Moriarti they constracted small-scale microwave antenna. Define the power radiated by this antenna required for distirbing Prof. Dowell internal head currents from the distance of several meters. Take the following assumptions:
-
The bulk and surface currents within prof.'s head are of the order of microampere.
Consider the following models of the prof.'s head:
:
- Sphere filled by water
( dielectric permittivity  , conductance  ).
- Sphere made from wet wood
( dielectric permittivity  ,
conductance  ).
- Superconducting sphere.
