The use of high permittivity materials (HPMs) can
improve coil performance at ultra high field. Much
recent experimental work performed with HPMs has been
done with prefabricated coils and/or standardized
clinical coils, built without the use of dielectric
materials in mind. However, close-fitting transmit
arrays are at risk of interacting closely with the HPM,
and therefore having their performance in the presence
of the HPM affected. Here we explore how HPMs proximal
to a set of three geometrically decoupled coils affect
their performance and decoupling.
