Electromagnetic Field Theory

A dipole antenna was radiating with some excitation in free space radiating a certain amount of the power. If this antenna is immersed in a lake where water is non-dissipative but has a dielectric constant of 81, the radiated power with the same excitation will

decrease to finite non-zero value

remain the same

increase

decrease to zero
