Theory of a high impedance coil (HIC) - a cable loop antenna with a modified shield - is comprehensively discussed for MRI application in both transmitting and receiving regimes. Understanding a weakness of the previously reported HIC in transmitting regime. we suggest another HIC which is advantageous in both transmitting and receiving regimes compared to a conventional loop antenna.... https://chefesquipmenters.shop/product-category/conveyor-toasters/
