Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

Density, Temperature and Frequency Dependent Model of the Dielectric Map of the Martian Surface

We report on laboratory electromagnetic characterization of several hyper-dry synthesized and field collected Mars analog soils that match the type of soils identified by the TES [1] and OMEGA [2] on the Martian surface in order to experimentally investigate the dielectric properties of the sediments covering the Martian surface at the frequency range from 1 to 1000 MHz. Measurements were perfo...

Analysis of Dielectric Relaxation in Water at Microwave Frequency

A distribution function has been incorporated into polarization and the information about the distribution function has been obtained from the experimental results of water and from the existing theoretical models for dielectric dispersion. The theoretical values of the relaxation terms obtained from Davidson-Cole equation are very close to the relaxation terms evaluated from the experimental d...
