Variable-temperature microwave dielectric properties of singlecrystal fluorides
Abstract
<p>Lithium, calcium, magnesium, and barium fluorides have widespread use in UV, IR, and scintillation applications. Although their optical properties have been well-studied, little data exist on their dielectric properties at microwave frequencies. Microwave dielectric properties of single-crystal LiF, CaF2, MgF2, BaF2, and SrF2, synthesized by Stockbarger melt-growth techniques, are measured using cylindrical specimens as TE <sub>01δ</sub> dielectric resonators enclosed in a cylindrical cavity. Single-crystal permittivity and dielectric loss tangent were evaluated at fixed frequencies between 7 and 9 GHz and over a temperature range from -75 to 150°C. The real permittivities of the measured fluorides increase quasi-linearly with temperature, permitting evaluation of the thermal coefficients of permittivity. The dielectric loss tangents increase approximately linearly with frequency, so that Qf (GHz) products at room temperature for BaF <sub>2</sub>, SrF <sub>2</sub> , CaF <sub>2</sub>, LiF, and MgF <sub>2</sub> (normal to c-axis) are 57600, 73000, 92000, 192400, and 458600, respectively.</p>
