Sketch electric field of beamed antenna.

AI Thread Summary
The discussion centers on sketching the electric field of a highly directional antenna that emits linearly polarized radiation in a narrow beam. Participants explore whether the provided sketch accurately represents the electric field in the plane containing both the electric field and the beam axis. There is a question about the magnetic field's appearance, which is expected to be similar but rotated 90 degrees around the beam axis. The conversation also touches on the possibility of achieving the desired beamed radiation pattern through the arrangement of multiple dipole radiators aligned along a common axis. Overall, the thread seeks clarification on the relationships between electric and magnetic fields in the context of antenna radiation patterns.

Suppose we have an antenna which has large directional gain. Suppose the antenna broadcasts linearly polarized radiation in a narrow beam and at constant frequency. Sketch the electric field in the plane which contains both the electric field and the beam axis. Does the attached come close?

Will the magnetic field look similar but rotated a quarter turn about the beam axis?

Given the electric field work backwards and sketch the vector potential.

Thanks for any help!

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
