scattering matrix of a dipole
Consider the following dipole: I want to calculate the s-matrix of this circuit: i think it is \$ b = S a \iff S = \frac{b}{a} = \frac{z_L - 1}{z_L +1}\$ with \$ z_L = \frac{Z_L}{Z_o} \$ But ...

Avoiding thermal noise to enter low temperature while not using dissipative element
Let's assume that we want to interact with a circuit at very low temperature \$T2\$ to avoid any source of noise. The voltage interacting with this circuit must have a specific target value \$V0\$. ...
