针对电磁屏蔽针织物屏蔽效能在平面状态下测试时,其结果难以满足针织服装评价要求的问题,本文提出一种基于屏蔽效能矢量的针织物屏蔽效能的计算模型,可计算电磁屏蔽针织物在曲面形态时的理论屏蔽效能。首先根据电磁波的反射及透射原理分析决定曲面形态针织物屏蔽效能的因素,提出将曲面针织物分解成多个微小理想平面并将屏蔽效能作为矢量处理的新论点。据此构建曲面针织物屏蔽效能计算模型,推导了模型的具体计算方法,并给出一个应用实例。理论分析显示,该模型将屏蔽效能作为矢量分析并将曲面分解成若干理想平面来计算曲面针织物屏蔽效能的方法是科学和正确的,为计算复杂形态的电磁屏蔽针织物的屏蔽效能提供了一种新的思路。

The shielding effectiveness of electromagnetic shielding fabric is always tested in a flat state , so the testing results cannot meet the evaluation requirements of 3D knitted fabric. The paper proposes a kind of calcula-tion model of knitted fabric shielding effectiveness based on vector , which can calculate theoretical shielding effec-tiveness of 3D surface. Firstly, it analyzes the main affecting factors of shielding effectiveness according to the electromagnetic wave reflection and transmission principle , and also proposes a new argument that 3D fabric can be divided into many tiny ideal planes and the shielding effectiveness is considered a vector processing. Secondly , the shielding effectiveness calculation model is built, and an application example is given. The theoretical analysis shows that the calculation model provided in the paper is scientific and correct , which will provide a new idea for calculating shielding effectiveness of complex surface electromagnetic shielding knitted fabric.
