Documents / Official release
This Defense Intelligence Reference Document, DIA-08-1004-006, is dated 6 April 2010 and was prepared by the Defense Intelligence Agency's Defense Warning Office. It is one of a series of advanced technology reports produced in FY 2009 under the Advanced Aerospace Weapon System Applications Program. The report reviews electromagnetic and optical metamaterials and their uses in sub-diffraction imaging, component miniaturization, energy harvesting, optical isolators and tunable devices. It concludes that metamaterials remain academic but have great potential for aerospace applications.
From the source: Release of 2026-09-18 Incident: 4/6/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD surveys metamaterials, engineered structures designed to control electromagnetic waves in ways ordinary materials cannot, and argues that their main aerospace value lies in unusual optical and microwave properties together with significant component miniaturization. The report reviews possible applications including sub-wavelength imaging, compact waveguides and lasers, energy harvesting, tunable absorbers, nonreciprocal devices, and switchable materials, with particular emphasis on infrared and microwave uses for sensing, power management, and payload efficiency. It notes that many of the most ambitious applications depend on the practical output of a still-nascent field, especially in optical metamaterials, where only limited demonstrations had been achieved and fabrication remained a major constraint. The document presents metamaterials as a promising advanced materials field with credible niche applications and broader long-term potential.

Figure 6. Schematic of the SiC-Based Super-Lens Which is Imaging Sub-Wavelength Holes Buried Under
the Si02 Layer. The imaged objects are >../20 holes milled in gold using FIB . The scattered signal is picked up by
the tip of an NSOM and directed towards the I R detector. Depending on the imag ing wavelength, either amplitude
(e) or the phase (f,g) of the signal are prominent.
As the laser beam scatters off the sub-wavelength holes, its electric field is picked up
by the tip of a Near-Field Scattering Optical Microscope (NSOM) and re-scattered into
the far-field. There it is interfered with the reference pulse and picked up by an infrared
detector. Note that this interferometric technique enables one to extract both the phase
and amplitude of the field, as shown in Figure 6. This significantly broadens the spectral
range over which the super-lens yields meaningful information . For example, the
amplitude contrast is highest at A = 10.85 μm shown in panel ( e) while the phase
contrasts are the highest at A =11.03 μm and A =10.65 μm.
