Incident voltage and reflected voltage
WebA reflected wave pulse can travel toward -x with the velocity u =−1LC. The voltage and current in this wave are related as VZirkr=− . At any point on the transmission line the voltage V and the current i are the sum of the voltages and currents in the positive and negative going, i.e. incident and reflected, waves. Thus VV V=+ri, and i r ri ... WebAt the short end, a wave with negative voltage travels back. That explains the sum of voltage is zero. The back traveling wave also has a current, and the sum is twice the initial current.

WebWhen an incident voltage wave E arrives a short circuit, the reflected voltage wave must be – E to satisfy the condition that the voltage across the short circuit is zero. The waves are shown in Fig. 8.7: 2. Open-Circuited Line:
WebReflection coefficient is the ratio of reflected voltage E reflected to incident voltage E incident, and is represented by the symbol Γ (gamma) or ρ (rho). The value of Γ can range from 0 for a reflectionless load, to 1 for a completely reflecting load (short circuit, open circuit, or pure reactance). Mathematically, reflection coefficient is WebMay 22, 2024 · This can be rearranged as the ratio of the reflected voltage to the incident voltage: V − 0 V + 0 = ZL − Z0 ZL + Z0 This ratio is defined as the voltage reflection coefficient at the load, ΓL = ΓV L = V − 0 (0) V + 0 (0) = V − 0 V + 0 = ZL − Z0 ZL + Z0 That is, at the load V − 0 = ΓLV + 0
WebIn telecommunications and transmission line theory, the reflection coefficient is the ratio of the complex amplitude of the reflected wave to that of the incident wave. The voltage and … WebDec 21, 2024 · Reflected power (p) = 100 * Γ². In order to use this formula, we must first find Γ from the value of VSWR and use it to find the reflected power as a percentage. We can also extend this to find the through power percentage by subtracting the reflected power percentage from 100%. Through power percentage = 100% - Reflected power percentage
