Description
I will talk about the matrix that is between an electric field of an antenna and the voltage it induces on the antenna back-end. It is commonly known in radio astronomy as the E-jones matrix, but in fact it is not a Jones matrix since it has dimension length. I connect the E-jones in radio observations to effective length of antenna theory. I also extend the embedded element pattern to the embedded antenna length, thus clarifying its true nature. A beam model fundamentally is determining the effective lengths of all a telescope's antennas.
