This letter studies the mainlobe misorientation problem of the First-Order Steerable Differential Array (FOSDA) in the presence of microphone gain and phase errors, whose response is constructed by a ...

It is demonstrated that this can be achieved by employing mixed-order elliptic filter arrays where the different orders of the filter are responsible for different tunable ranges of the phase shift.

The computer simulations show that the higher-order plasmon modes can be excited much more effectively in the array of FET units with separate channels and combined source and drain contacts then in ...
