The tidy3d.PointDipole source placed in a lossless homogeneous material injects power close to the analytically expected result for an infinitesimal antenna with oscillating current. There can be a small difference from the analytical result due to the finite grid, which disappears in the limit of high resolution. To calculate the radiated power of a dipole in the presence of dispersive, lossy, or non-homogeneous materials, you can use a tidy3d.FluxMonitor box. Refer to this notebook for an example.
