Measurement of Dielectric Parameters of Small Samples at X-Band Frequencies by Cavity Perturbation Technique

A microwave absorber based on strontium ferrite–carbon black–nitrile rubber for S and X-band applications

“…Permittivity and permeability were calculated employing cavity perturbation technique equations cited in Refs. [19][20][21][22][23]. The instrument was calibrated using a standard dielectric material with known properties (FR4 glass epoxy).…”

Measurements of Dielectric Parameters of Aviation Fuel at X-Band Frequencies Using Cavity Perturbation Technique

“…When the samples are smaller than the height of the cavity, accurate measurements are often difficult [11]. The objective of cavity perturbation technique is to measure accurately and precisely the quality factor Q and resonance frequency f o of unloaded and loaded microwave cavity resonator using transmission or reflection coefficient (s-parameters) as a function of frequency [12][13][14].…”

“…Thereafter many researchers have reported theoretical and experimental analysis of cavity perturbation techniques [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The measurements of complex permittivity ( * ) and permeability ( * ) are performed by inserting a small,…”
