DIELECTRIC PROPERTIES OF DATES AT 2.45 GHz DETERMINED WITH A TUNABLE SINGLE-MODE RESONANT CAVITY

摘要

A tunable TM_012 mode resonant cavity with an additional tuning mechanism and working at 2.45 GHz has been designed, fabricate and tested for determination of dielectric properties of dates. The cavity has a Q-factor > 5000, and a tuning mechanism which gives it more flexibility and controllability. The cavity has been used for determining the dielectric Properties of Rezaiz, the most common type of dates used in The production of date juice in the Eastern Province of the Kingdom of Saudi Arabia.
