Abstract
The invention discloses a method for integrating a multi-beam-frequency-invariant conformal array, and relates to an artificial electromagnetic device. The method comprises the following steps: integrating three beams by using an EGMPM algorithm to obtain a linear antenna array system with frequency invariance, thereby obtaining point source excitation and point source spacing of the linear antenna array system in a virtual space; obtaining a mapping relation from a virtual space to a physical space by setting a Laplacian equation and boundary conditions, the mapping relation being represented by a Jacobian matrix J, mapping each point source position to an actual conformal lens through conformal transformation, and keeping the amplitude of the point source unchanged; setting a relative dielectric constant of the conformal lens through a Jacobian matrix mapped between the virtual space and the physical space; according to the antenna reflection theory, setting a foam layer at the bottom end of a bottom array element placement position of an antenna array, and adjusting the relative dielectric constant of the area, so that a multi-beam-frequency-invariable conformal array is realized. The cost is saved, and the flexibility and applicability of the antenna array are improved.
Description
Technical field[0001]The present invention relates to an artificial electromagnetic device, and more particularly to a method of integrated ambient array of integrated multi-beam-frequency constant.Background technique[0002]In many devices, the weight of each point source of the antenna array has a strict limit, thus derived a number of antenna optimization techniques to change the layout of the antenna array to achieve the expected beam map. In this, the extended Generalized Matrix Pencil Method, EGMPM, which can be entered from the matrix beam method, is a multi-beam and a linear array that maintains beam-constrained within a certain frequency range. However, most of the antenna optimization techniques are implemented in a linear array or a flat array without being applied to a common array. Transform Optical As an effective means of handling electromagnetic waves, it has been widely used in designing various new types of electromagnetic and optical devices. Based on its help, the...
