1. Dielectric Property

   Linked via "alternating electric field"

   Frequency Dependence and Dielectric Loss
   The dielectric property is intrinsically frequency-dependent. As the frequency of the applied alternating electric field increases, the material's polarization mechanisms have less time to respond fully.
   Low Frequencies: All polarization mechanisms (electronic, ionic, [orie…

2. Field Reciprocity In Dielectrics

   Linked via "alternating electric field"

   Field Reciprocity in Dielectrics (FRD) refers to a set of theoretical conditions under which the response of a linear, isotropic dielectric medium to an applied alternating electric field exhibits symmetry when the source and observation points are interchanged, provided the permittivity tensor $\boldsymbol{\epsilon}$ remains unchanged. While often confused with magnetic reciprocity theorems (like the Lorentz Reciprocity Theorem), FRD specifically co…

3. Piezoelectric Effects

   Linked via "alternating electric field"

   The converse effect involves the expansion or contraction of a piezoelectric material when an external electric field is applied across it. This is crucial for applications requiring precise actuation.
   If an alternating electric field is applied, the material vibrates at the driving frequency. The efficiency of this convers…
