The magnetoresistance Rxx was investigated in arrays of abutted square cavities with lengths L ranging from 500 nm to 1.2 ìm near filling factor í = 1/2. Maxima in Rxx occur for effective magnetic field values satisfying the magnetic focusing condition between the cavity spacing and the cyclotron radius of composite fermions, also for the effective magnetic field direction when ...
