SHIELDING METHOD AND APPARATUS USING TRANSVERSE SLOTS

摘要

A shielding method and apparatus for providing predetermined attenuation of one or more electromagnetic energy field components as the field components interact wit h the shield. The shield composed of a flexible strip or cylindrical body and respectively comprising a transverse conductive element or a transverse slot therein. The shields bein g adapted to cover an antenna mounted on a support. The shields being compatible for use in conjunction with saddle, tilted coils or multi-layered tri-axial coils to produce a pure transverse magnetic dipole electromagnetic field.
