As electromagnetic waves are affected by electrical conductivity or permittivity, they are widely used to evaluate geotechnical characteristics. In this study, a probe for measuring electromagnetic waves using a time domain reflectometry is manufactured to evaluate heavy metal concentration in salin...

전자기파의 특징은 무엇인가? | 전자기파는 주변 매질의 특성에 민감하게 반응하는 전파 특성을 가지고 있다. 이와 같은 이유로 지반공학분야에서 전지기파를 이용한 연구가 활발히 수행되고 있다. | |
매립장의 침출수는 어떤 문제를 야기하는가? | 매립시설에서 침출수는 주변 환경에 가장 유해하게 작용하는 요소로, 유출 시 지반 및 지하수 오염과 같이 치명적이며 지속적인 문제로 작용한다. 일반적으로 매립장의 침출수에 대한 모니터링을 위해 침출수 집배수 시설이나 누출검지 시스템, 처리시설 등을 사용하고 있으며 추가적으로 이에 의한 오염을 방지하기 위해 차수막을 설치하도록 하고 있다. | |
시간영역반사법이란 무엇인가? | 전송선에 전자기파가 전파할 때 전송선에 전기적인 임피던스 변화가 발생하면 신호가 반사된다. 이렇게 반사된 신호를 측정하는 기술을 시간영역반사법이라고 한다. 전송선은 전원과 전기적 부하를 이어주는 연결선으로 유전체를 사이에 둔 두 개의 전선 구조를 의미하며, 대표적으로 동축 케이블(coaxial cable)이 있다. |
