A system consisting of two quantum dots connected to separate reservoirs is studied and electron transport properties are investigated in the Kondo regime with use of the non-equilibrium Green function technique based on the method of equation of motion. As the orbital quantum number is conserved during tunnelling processes when each dot is attached to its own leads, the orbital SU(2) Kondo effect is observed. It is shown that the mixing between the leads strongly modifies transport properties leading to a considerable suppression of the Kondo resonance.
