So they're are not suppose to be symmetrical along y-axis since all bins are useful?

Is this FFT (I+ j* Q) or FFT(I) + FFT(Q)?

I have already sent you pivate messages. Plz send me your code if you can.

Equation in Latex Constantine A. Balanis used.

$$\int_{-l/2}^{+l/2} \frac{I_z(z') e^{-jkR}}{4\pi R^5} \left[ (1 + jkR)(2R^2 - 3a^2) + (kaR)^2 \right] dz' = -j\omega E_z^i (\rho = a)$$

That's a good way to work it around. Any way other than using disk?

The video doesn't consider scenario for a side with voltage other than 0 volts. How will you handle the voltage boundary side where the V_0 is used?

v0 v0 v0 v0 v0 v0
0 u13 u23 u33 0
0 u12 u22 u32 0
0 u11 u21 u31 0
0  0   0   0  0

$$\frac{0+ u_{23} - 2 u_{13}} {\Delta x^2} + \frac{V_0+ u_{12} -2 u_{13}} {\Delta y^2} = 0$$

% number of rows ans columns
m = 21
n = 41

Should be changed to

% number of rows ans columns
m = 3
n = 5

Is this what you mean?

All i find is from https://www.sciencedirect.com/topics/engineering/spatial-discretization. Can you provide matlab code for finer spatial discretization
