How to ^2 or ^more for signal source from GRC

Does anybody knows how to power(^) the signal from the signal source
block or USRP source
for example signal from signal source are coswt+jsinwt or Ae^(jwt) and i
want to ^2 for the result = (Ae^(jwt))^2
Does the grc blocks have a ^ block?

Thank you very much for yours advice

There is no single block to do this. But consider that x^2 = x*x. So
use a multiplier with two inputs each coming from the signal of
interest.

For x^n, you can connect n inputs into the multiply block.

FWIW, there’s

gr.complex_to_mag -> computes sqrt(z * z) for complex z
gr.complex_to_mag_squared -> computes z * z for complex z
