Theorem: tan delta(eps'' = 0) = 0 (lossless-dielectric loss-tangent vanishing)

Theorem (loss-tangent-lossless canonical): tan δ = ε''/ε'; at ε'' = 0 (lossless dielectric) tan δ = 0/ε' = 0 identically. Canonical sympy pin: eps_dp = sp.Symbol('eps_dp', real=True); eps_p = sp.Symbol('eps_p', positive=True); tan_delta =…
