任意旋轉(zhuǎn)對稱面共形陣互耦的分析
ANALYSIS OF MUTUAL COUPLING OF CONFORMAL ARRAYS ON ARBITRARY SURFACES WITH REVOLUTIONAL SYMMETRY

摘要: 本文研究了旋轉(zhuǎn)對稱面共形陣互耦的分析方法。文中提出了等效環(huán)的概念,把旋轉(zhuǎn)對稱面上不等元分布共形陣等效為等元分布的情形,簡化了共形陣的物理模型。通過把陣的任意激勵分解成與結(jié)構(gòu)對稱性相匹配的一組本征激勵的線性疊加的方法,避免了大矩陣的求逆,大大的減少了運(yùn)算量。這對于共形陣的分析和綜合有重要意義。

Abstract: This article presents the mutual coupling of conformal array on arbitrary surfaces with revolutional symmetry. The concept equivalent ring simplifies the array model in the method of equating arrays with unequal elements to arrays with the same elements in each ring. The method of decomposing the arbitrary excitation of arrays into a term of intrinsic excitations aviods the inversion of large matrixes and so reduces largely the computer tune, which is very important to the analysis and synthesis of conformal arrays. -
