Disclosed apparatuses, systems, and materials relate to the disassociation of feedstock species (such as those in gaseous form) into constituent components, and may include an energy generator configured to provide a microwave energy. A first chamber defines a first volume and is configured to guide the microwave energy along the first chamber as a sinusoidal wave having an energy maxima at a point along the first chamber. A second chamber contains a plasma plume and is positioned substantially proximal to the first chamber, and is configured to enable propagation of the microwave energy through the first chamber and the second chamber such that the microwave energy demonstrates, at a radial center of the second chamber, a coaxial energy maxima configured to ignite the plasma plume contained in the second chamber. Carbon-containing materials may be formed by controlling flow parameters of the feedstock species into the first or second chamber.
