Compute power density using provided power, gain, and distance values. It benefits radio frequency (RF) applications and electromagnetic field analysis.
Effortlessly determine real power and volt-ampere reactive (VAR) through inputting voltage and current values. Applicable to both single-phase and three-phase power systems, this calculator aids in identifying actual power and reactive power.
RF Power Density formula
![\[S = \frac{P \cdot G}{4 \cdot \pi \cdot R^2}\]](https://x-calculator.com/wp-content/ql-cache/quicklatex.com-7d4575b5636eff53526d578e6385c833_l3.png "Rendered by QuickLaTeX.com")
Where:
- S = Power Density,
- P = Power Input,
- G = Power Gain,
- R = Distance to the Center of Antenna,
- PI = 3.14
