Global optimization method for quasi-optics multiple diodes power combiner

In this paper we use quasi-optical techniques, millimeter techniques and a global optimization method techniques to design a higher fundamental mode power, larger fractional power of fundamental mode power and greater combining efficiency quasi-optical power combiner. The structure of the quasi-optical power combiner includes a spherical reflector, the radius of curvature of which is R and a hybrid reflector that is called the input reflector. The monolithic source-array is made up of 25 Gunn diodes that are mounted of parallel brass bars that have low thermal resistance. The bars are fixed on the inner plane surface of the hybrid reflector that is made up of a plane and a spherical surface with radius of curvature R
