Embodiment Construction

[0065] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] The present invention is a method for designing the aperture space of a honeycomb wave-absorbing structure. The principle is: firstly, the closed-form expression of the equivalent electromagnetic parameters of the honeycomb wave-absorbing structure with dispersion characteristics is used to replace the traditional closed-form expression, wherein the dispersion characteristic function part is Neglected in the traditional closed-form theoretical expression; and then introduce the linear least squares method to establish the functional relationship between the unknown undetermined coefficient and the coating thickness in the closed-form dispersion expression; then, based on the transmission line theory, the reflection of the honeycomb absorbing structure is given Finally, according to different design objectives, by setting different objec...

Abstract

The invention discloses a design method of aperture space for cellular absorbing structures which is carried out according to the following steps: step 1: establishing the functional relationship between the unknown undetermined coefficient and the coating thickness; step 2: calculating the reflectivity of the cellular absorbing structure; step 3: setting the objective function and optimizing the function. The invention improves the accuracy of equivalent electromagnetic calculation of the cellular absorbing structure in the wide band while reduces the error of calculating the reflectivity due to the error of the equivalent electromagnetic parameters, thereby improving the accuracy of the design result. The invention overcomes the problem that the closed-form expression of the dispersion characteristic can not be directly used due to the existence of the unknown coefficient.

Description

technical field [0001] The invention belongs to the technical field of electromagnetism, and in particular relates to a method for designing an aperture space of a honeycomb absorbing structure. Background technique [0002] As a typical representative of multifunctional radar absorbing materials, radar absorbing structure is a multifunctional absorbing material developed on the basis of traditional radar absorbing materials with both absorbing performance and carrying capacity. The honeycomb radar absorbing structure, also known as the honeycomb absorbing structure, has always occupied a very important position in the stealth design of various weapon platforms due to its advantages of light weight, high strength, and low density. After decades of hard work by engineers and scientists, a relatively complete theoretical system for the analysis, design and manufacture of cellular absorbing structures has been formed. With the help of this system, anyone can easily design the ...
