Variety of attenuation of RF suppression filters Open
Differential mode attenuation of RF suppression filters can be measured directly. Alternatively, this attenuation can be derived as modal S-Parameters from the S-Parameters measured for the single multiport paths which in fact the filter i…

Diversity Pertaining to the Attenuation of the RF Disturbance Suppression Power Line Filters Open
Filters for the suppression of the RF disturbances in power lines are passive; wideband stop filters attenuating common as well as differential disturbances should be insensitive to the variation in the impedance at the input and the outpu…

Fabrication and application of electrically conducting composites for electromagnetic interference shielding of remotely piloted aircraft systems Open
Electromagnetic interference (EMI) is the phenomenon occurring in remotely piloted aircraft systems, especially in the radio-frequency band emitted by motors and power supplies, that needs to be shielded in order to avoid disturbances in c…
