The Tailored Force Fields technology offers the potential of automatically assembling structures of specified wall shape in microgravity using resonant acoustic or electromagnetic fields. Scaled to radio wavelengths, it opens a way to build large radiation‐shielded space stations. The scientific logic behind the technology is summarized in this paper. Experimental evidence in acoustics, ultrasonics, optics and microwave regimes is tied to first principles. Results show that the dominant features such as the forces on particles are predictable to good accuracy using simple solutions of the conservation equations. The detailed formation of walls involves secondary interactions between particles, an area requiring further modeling. Evidence to‐date indicates that the interactions cause, if anything, attractive forces under the conditions of interest. However, the detailed particle behavior depends on the specifics of the materials and the wavelengths being used. Phenomena such as heating and surface sintering are seen to be possible to integrate into, or separate from, the force‐field tailoring.
