Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFFresnel reflection coefficient
- The electric field intensity of the reflected and transmitted waves may be related to the incident waves in the medium of origin through the Fresnel reflection coefficient.
- It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors.
Field Reflection Coefficient
- This coefficient (often denoted as R) represents the fraction of the incident electric field intensity that is reflected when a wave encounters an interface between two different media.
- It is defined as: \(R={E_r\over E_i}\) where Er is the electric field intensity of the reflected wave, Ei, and is the electric field intensity of the incident wave.
Signal Attenuation
- This refers to the reduction in signal strength (or intensity) as the wave travels through a medium, but it does not specifically describe the relationship between incident and transmitted electric fields.
Free Space
This term refers to an ideal vacuum environment where electromagnetic waves can propagate without loss, but it does not represent a specific coefficient related to transmission or reflection.
