An incident wave emanates from a source of wave production. If there is a boundary from which this wave is reflecting, the returning wave is known as the reflected wave.Using the conservation of energy or, equivalently, power, the incident power on a target equals the reflected power. The incident power is the incident signal intensity multiplied by an effective cross-sectional area, σ. The reflected power is the reflected signal intensity multiplied by the area of a sphere of radius R centered on the target ...

Power in space couples into circuits, and vice versa, via antennas which couple energy between these two media by matching their (generally different) impedances. The relationships among the power in a circuit, the incident or radiated power in space around the circuit, and the characteristics of an antenna that couples the two are completely

Incident power irradiance (P in) J SC, V OC and FF can all be measured directly from an I-V curve measurement. When measuring solar cells, we often refer to current density, J, rather than just the current, I.

Incident sunlight is usually thought of in terms of power per unit area. The typical units are mW/cm 2. At the earth's surface, the nominal value of the solar constant is 137 mW/cm 2. This value corresponds to high noon with the sun directly overhead (as would occur at the equator or in the tropics).

10.5: Oblique Incidence. When a plane wave falls upon the plane interface between two media the incident and reflected wave-vectors define the plane of incidence, see Figures (10.4.6) and (10.5.7).
