hi there, I am stuck on this question can some give me a hint on how to solve the question:
the question is:
Calculate the skin depth for copper at 1.0 GHz . σ = 5.8x10^7 S/m, εr=1, μr=1.
the formula i think that i need to use is
tan δ = σ / (ω)(ε0)(εr)
ω = 2nf = 2 x n x 1 x 10^9
ε0 = 8.85 x 10^-12
er = 1
where do i put μr?
im missing a another step but i don't no what, can some give me a hint please?
the answer to the queation is
tan δ >>1, d = 2.1um
