NSTL evaluation of the compact EMC chamber with ferrite tiles being partially lined on the floor ground
2002
Compact fully anechoic chambers may gradually replace open area test sites as the preferred type of testing facility for the measurement of radiated emissions. Based on FDTD modeling approach, a numerical tool with the measuring tunable dipole antennas being considered is established to simulate the NSTL performance of the compact EMC chamber with different layout design of ferrite tiles. This paper theoretically and experimentally investigates the suitability of a compact fully anechoic chamber with ferrite tiles being partially lined on the floor ground as a free-space environment at frequency range below 300MHz. Furthermore, several designs of reduced coverage of the ferrite tiles in the compact chamber are proposed and discussed.
