Its main improvement with respect to the traditional collimating-beam design in the reduction of interferometric noise in almost one order of magnitude without increasing insertion loss. It has applications in multiple-point pollutant and chemical species detection.}, publisher = {URSI 1997, XII Simposium Nacional de la Unión Científica Internacional de Radio, Bilbao, v.
