Abstract: Various embodiments of the present invention are directed towards a simulant and method relating to producing a simulant. For example, a simulant of a target threat includes at least one component ingredient characterized by a corresponding component loss factor that is essentially zero. The simulant is configured to exhibit a simulant dielectric constant corresponding to a simulant reflectivity substantially equivalent to a threat reflectivity. A method of producing a simulant of a target threat includes generating an ellipse-like curved solution space corresponding to a plurality of candidate threat reflectivities, identifying a threat dielectric constant, from among respective threat dielectric constants of the candidate threat reflectivities forming the curved solution space, and identifying at least one weight proportion of at least one corresponding simulant ingredient.
