Popis: International audience; For heterodyne array receivers, phase gratings are useful to divide the local oscillator (LO) signal into several beams to pump the mixers of an array. We have developed a computer model to compute general phase profiles that can be non periodic. The model allows to set many input parameters and constraints so that the output can be optimized for any specific case. The phase profiles can be used to design phase gratings that can be used in transmission or in reflection.
