Abruptly turning off the source will introduce high-frequency artifacts
into the simulation as mentioned previously. High frequencies near the
Nyquist frequency of the grid have slow group velocities and are poorly
absorbed by PML. This is why the fields do not go to zero after the
sources
Hello MEEP users,
I am facing problem with Harminv Function.
In my code I am simulating a TM111 mode in cylindrical
resonator(r=10mm, h=20mm) for which the eigen-frequency is 19.44 GHz.
But Harminv is giving a frequency of 18.85GHz. Setting a sharp width is
also not helping.
Moreover I have
(set! k-point 1 1 0) will set bloch vectors as (1 0 0) (0 1 0) or (1 1 0)?
What is the difference between (set! k-point 0 0 0) and (set! k-point 1
1 0) ?
