Exotic types of polarization
I am aware that in the classical approximation of electromagnetic waves, waves can be linearly polarized (so that the B-field oscillates in one dimension as $B=B_0\cos(\omega t)$), circularly ...

What is the radiation pattern for an electric dipole rotating in the horizontal plane?
In trying to answer $\sigma$ transition and angular momentum conservation the following question arose.
Suppose we have an electric dipole $\boldsymbol{d}$ which is oriented and rotating within the ...

Polarization of Patch antenna - Intuitive explanation
I was looking into the polarization of patch antennas (for GNSS use).
I found this website (http://kempbros.github.io/antennas/Patch_Antenna_Generator/) which gives the geometry of the antenna ...

Simplified model of antenna polarization loss
I need to write a very simple model to estimate the $dB$ value of the polarization loss between two antennas (in realtime).
Such antennas are common (yet identical) omnidirectional dipole antennas, ...

Far field horizontal polarization component of a dipole antenna
An infinitely thin dipole radiates an electromagnetic wave which in the far field is vertically polarized, with zero horizontally polarized component. I am trying to understand what happens when the ...
