Loss angle is dimensionless and interpreted in degrees.

This should be “Loss tangent”, not “Loss angle”
Loss tangent has angular units, not dimensionless.

Also, there needs to be a different loss tangent for Young’s modulus and for the Tension, so the complex value for E (Young’s modulus) in the computations would be:

E = Eo * exp(j*loss_tangent_E)

and for the Tension,

T = To * exp(j*loss_tangent_T)

where I’ve used “o” to denote the magnitude (i.e. Eo=|E|), _E to refer to the Young’s modulus, and _T to refer to the Tension.

I guess we can refer to the two different loss tangents as:

• “Young’s modulus loss tangent” and
• “Tension loss tangent”
