    EM re-radiation from a metal object (antennas)

    I made the switch open so that it would depict the situation when they are the same.

    EM re-radiation from a metal object (antennas)

    Ok. should have been clearer about that. Then we agree. Not sure I follow your analogy with a capacitor. Are you thinking of the circuit equivalent of a dipole antenna? Do you not consider the two arrangements below to be "equivalent"? That the same current will flow inside the antenna...

    EM re-radiation from a metal object (antennas)

    Thanks for the explanation. But this makes me a bit confused. Doesn't an electromagnetic wave always induce current to flow back and forth in a thin solid linear conductor (assuming it is directed along the E-field)? With a resonance maximum when the conductor is λ/2 long? Can't a solid linear...

    EM re-radiation from a metal object (antennas)

    Consider the following situation. Two identical monopole antennas are placed in a field with distance d. One of them is used to receive signals and the other is disconnected and can therefor be considered to be just a metal rod (my guess). A plane wave of a single frequency is coming from a...
