Dielectric Properties of 1-ethyl-3-methyl-imidazolium Tetrafluoroborate (EMIM-BF4) Using Cole-Cole Relaxation Model

T. J. Ikyumbur, E. N. Asagha, E. C. Hemba & J. A. Bash · Physical Science International Journal · 2017

The Cole-Cole relaxation equations were derived from the Debye equation. The dielectric constant E’ and loss factor E” of EMIM-BF4 were fitted using the derived equations at temperature range of 5°C to 65°C and frequency range of 0.1GHz to 10GHz. The result obtained shows that th...
