1. Sinsoidal Wave in a Lossless Medium

정방향 진행파
역방향 진행파

 

A : amplitude [1]

T : time period [sec]  ↔ ω : angular frequency [rad/sec]

λ : wave length [m] ↔ k : wave number ↔ β : phase constant [rad/m]

 

※ General Case

Φ : reference phase

lead(Φ>0)vs. lag (Φ<0)

※ Phase Velocity

u_p : phase velocity, propagation velocity

 

2. Sinsoidal Wave in a Lossy Medium

α : attenuation constant, attenuation factor [Np/m] [dB/m]
