In this work, we intend to calculate spin conduction matrixes of T-shaped spin circuits' branches. Also we investigate simultaneously effects of gold nano-channel length and cross section area variations on its non-zero elements. Our findings show that   G₁₁ and G₂₂ elements of series branches increase with simultaneously channel length reduction and channel cross section area grow up. For spin flip branches, G₂₂ element decreases with simultaneously nano-channel length and cross section area reduction. We choose copper metal as nano-channel because of its high conductance and lattice constant.
