Howard Reader is a sabbatical visitor from Stellenbosch University, South Africa. Howard’s research group is primarily concerned with the management and mitigation of RFI for South Africa’s SKA demonstrators, KAT -7 and MeerKAT. In general terms, insight is gained through computational and scale modelling. However, fundamental EMC principles need to be applied at all levels of the system design if a “whisper-quiet” environment is to be achieved. During this seminar, elementary EMC issues will be illustrated through a series of apparently simple experiments which are primarily concerned with the question: “where are the currents flowing?” Twin-flex coupling, cable and equipment transfer impedance, B-fields around conducting boxes, apertures and EMC tools of the trade will be described.
