Summary:An electromagnetic wave measurement apparatus for estimating an electric field of a near field using an electric field of a far field restores a phase by using the magnitude of strength of the electric field of the far field, positions phase information from the far field to the near field using the restored phase information, and obtains the magnitude of strength of the electric field and power density of the far field and the near field at the same time, thereby having an effect of reducing costs for installing equipment. 원거리의 전기장을 이용하여 근거리의 전기장을 추정하는 전자파 측정 장치는 원거리의 전기장 세기의 크기를 이용하여 위상을 복원하고, 복원된 위상 정보를 이용하여 원거리로부터 근거리로 위상 정보를 위치 이동시켜 원거리의 전기장 세기 크기를 이용하여 원거리와 근거리의 자기장 세기의 크기, 전력 밀도를 동시에 획득할 수 있어 장비 설치에 대한 비용을 감소할 수 있는 효과가 있다.
