Characteristic impedance (often represented as \\( Z_0 \\)) is a fundamental property of a transmission line or waveguide that defines the relationship between the voltage and current of a wave traveling along the line when it is at steady state. It is determined by the line's physical and electrical characteristics, including its inductance per unit length (\\( L \\)) and capacitance per unit length (\\( C \\)).
