The main objective of this paper is to provide a brief and necessary background of dielectrics in the field of space technology. The mobile telephone, TV, Radio, Satellite or any type of modern communication is not possible without one type of antenna or the other and no radar works without an antenna. Antenna is a sensor of electromagnetic waves. Electric and magnetic fields exist in a dielectric...
Recently, we have developed and established the TDR technique in laboratory provides information regarding dielectric permittivity in the frequency range 10 MHz to 30 GHz. TDR method involves the generation of step pulse with rise time of 20 pico-seconds in a coaxial line system and monitoring the change in pulse shape after reflection from the sample placed at the end of the coaxial line. There is...
The values of complex permittivity for alcohol -dioxane mixtures with various concentrations have been determined in the frequency range of 10 MHz - 20 GHz using time domain reflectometry (TDR) method. TDR method involves the generation of step pulse with rise time of 25 picosecond in a coaxial line system and monitoring the change in pulse shape after reflection from the sample placed at the end...
