Electromagnetic Field Theory
Q1.

The electric fields of a UPW incident on an antenna is given as : {E_{inc}} = (\overrightarrow {{a_x}} + 5\overrightarrow {{a_y}} ){E_0}{e^{jkz}} while that of an antenna directed towards the incident wave is given as : {E_{ant}} = (\overrightarrow {{a_x}} + j2\overrightarrow {{a_y}} )\frac{{{E_I}}}{r}{e^{ - jkz}}

Find the polarisation of the two waves as well as the loss due to polarisation mismatch between the two waves :
