Abstract

This paper represents an simplified design method of hybrid composites. The proposed method is very simple compared to conventional design approaches and easy to apply to practical design problems. The method is based on not complex optimization approaches but conventional theories. The equivalent dielectric properties concept and multi-layered dielectric slab theory are an important theoretical background of the proposed method. This approach divide the design domain into several domain which have theoretically different electro- agnetic functionality. Then, the domains are expressed by equivalent dielectric properties. Numerical analysis are performed several types of design candidates. S-parameter test for final design was conducted for validate the proposed approach indirectly.

본 논문에서는 하이브리드 복합재를 전자기학적 성능을 단순화하여 설계하는 방법을 제안한다. 제안 방법은 전통적인 간단한 이론들을 바탕으로 하며 최적 설계 등과 같은 기존 하이브리드 복합재의 설계 방법들에 비하여 간단하다. 따라서, 실제적인 문제에 대하여 보다 쉽게 적용할 수 있다. 본 논문은 등가 유전율 및 다층 유전체에서의 전파 전송 이론을 이용한다. 우선, 설계 영역을 전자기학적 기능에 따라 몇 개의 영역으로 구분하고 각 영역을 등가 유전율로 표현하였다. 입사각 안정성과 투과 성능을 고려하여 가능한 유전율 조합을 산출하고 몇 번의 전자기 성능 해석을 통하여 기본 설계 형상을 도출하였다. 제안한 설계 방법의 타당성을 간접적으로 확인하기 최종 설계안에 대한 전파투과시험을 수행하였다.
