Electromagnetic Transmission Lines

Flashcards covering key vocabulary related to electromagnetic transmission lines, including definitions and technical terms.

Transmission Line

A specialized cable or other structure designed to conduct electromagnetic waves.

Load Impedance (ZL)

The impedance at which the transmission line is terminated, affecting reflections and input impedance.

Reflection Coefficient (Γ)

A measure of how much of a wave is reflected at an impedance discontinuity.

Input Impedance (Zin)

The impedance seen by a source at the input of a transmission line.

Phase Constant (β)

A measure of the phase change per unit length of a transmission line.

Electric Length

The physical length of a transmission line expressed in terms of wavelengths at a given frequency.

Voltage Source (Vg)

A device that provides a potential difference to drive current through a circuit.

Internal Impedance (Zg)

The impedance within a voltage source that affects how much current can flow when connected to a load.

Wave Propagation

The transmission of waves through a medium or space.

Lossless Transmission Line

A transmission line that does not dissipate power as heat, ideal for theoretical calculations.
