The design and implementation of systems that generate, control, modulate, and shield against specific frequency bands to achieve desired physical, biological, or informational effects. This goes beyond radio engineering to include: designing materials with metamaterial "frequency cloaks," building habitats that use resonant frequencies to simulate gravity on spacecraft, or creating agricultural fields optimized with growth-enhancing sound frequencies. It's engineering with a spectrum analyzer in one hand and a reality-altering blueprint in the other.
Example: A Dyson Sphere designed not just to capture light, but to modulate the sun's output frequencies—filtering harmful radiation, amplifying useful energy bands, and perhaps even using the star's oscillations for galaxy-wide communication—is a megascale project of Frequency Engineering. It treats a star not as a simple furnace, but as a complex, tuneable frequency engine.
