Engineered dielectric meta-materials

A strained dielectric material comprising at least one type of component containing a first domain wall variant type that is engineered in phase-co-existence with, or in close phase proximity to, i. a second phase state comprising at least a second component containing a second domain wall variant type or ii. a paraelectric state achieved at zero electric field, wherein the at least one type of component comprises one or more of an in-plane sub-domain polarization component or a plane-normal sub-domain polarization component, characterized in that, the at least one type of component is engineered such that the strained dielectric material exhibits an increased tunability ratio based at least on being engineered in phase-co-existence with, or in close phase proximity to, i. the second phase state or ii. the paraelectric state achieved at zero electric field or over a finite range of non-zero electric field.
