Abstract: In this paper the generalized Fibonacci class zone plates with varying structural parameters are proposed to generate the fixed-position foci. Unlike the generalized Fibonacci and modified Thue-Morse zone plates, the proposed zone plate can generate more subsidiary foci and the construction method is applicable to many kinds of bi-focal zone plates. The construction method of the proposed zone plate is illustrated and the focusing property of the proposed zone plate has been verified with simulations. The Fibonacci, Thue-Morse, m-bonacci and precious mean sequences are the common bi-focal sequences. It was proved in the simulation that the position of one of the foci of a generalized Fibonacci class zone plate based on the common bi-focal sequence can be kept constant when the structural parameters change and the generalized Fibonacci class zone plates based on the common bi-focal sequences can generate more subsidiary foci along the optic axis, and the position of one of two main foci can be kept constant for two different generalized Fibonacci class zone plates based on the arbitrary-order common bi-focal sequences. The proposed zone plates can be applied to trap particles at the designated plane and generate a clearer image at the described position along the optic axis.

 

Keywords: Fibonacci class sequence, Generalized Fibonacci class zone plate, Fixed-position foci, Twin foci, Bi-focal zone plate.
