Implementation of Various Analog Filters in EM Wave Domain

In this paper, the variation of gain against the frequency of high pass filter, band pass filter, band reject filter in electromagnetic radiation domain, and electromagnetic shielding domain is compared. Electromagnetic wave domain on MA TLAB has been created, in which electromagnetic radiation is transmitted in negative y-direction, its electric field component is oriented in the negative z-direction and the magnetic field component is oriented in the negative x-direction. Analog high pass filter, band pass filter, band reject filter characteristics have been implemented in electromagnetic radiation domain. Then the comparison of characteristics of analog high pass filter, band pass filter and band reject filter in electromagnetic domain and electromagnetic shielded domain has been done. And the results acquired after comparison are inspected. After providing a shield to the high pass filter, band pass filter and band reject filter circuit, the original characteristics of the filter have been recovered.
