producer goods

or capital goods or intermediate goods

Goods manufactured and used in further manufacturing, processing, or resale. Intermediate goods either become part of the final product or lose their distinct identity in the manufacturing stream, while capital goods are the plant, equipment, and inventories used to produce final products. The contribution of intermediate goods to a country's gross domestic product may be determined through the value-added method, which calculates the amount of value added to the final consumer good at each stage of production. This series of values is summed to estimate the total value of the final product.

Intermediate-field region: For an antenna, the transition region--lying between the near-field region and the far-field region--in which the field strength of an electromagnetic wave is dependent upon the inverse distance, inverse square of the distance, and the inverse cube of the distance from the antenna. For an antenna that is small compared to the wavelength in question, the intermediate-field region is considered to exist at all distances between 0.1 wavelength and 1.0 wavelength from the antenna. Synonyms: intermediate field, intermediate zone, transition zone.
