Abstract
A design of the resonance spin finter is suggested in form of a quantum well with three quantum wires attached. Explicit formula is suggested for transmission coefficients accross the well in terms of the resonance eigenfunction of the Schredinger operator on the well with Rashba spin-orbital interaction.
