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 9. fSL Based on an Indefinite Permittivity Metamaterial Placed Between the Object and the
Image-Releasing Grating. The grating releases into the far field sub-diffraction waves produced by light
scattering off the object. The role of the meta material is to propagate sub -diffraction waves from object to grating .
(Reference 27)
Ever since Merlin's invention (Reference 28) of the sub-diffraction near-field plate, it
has become clear that the interference between sub-diffraction electromagnetic fields
can result in the formation of a deeply sub-wavelength image. The near-field plate,
however, is not an imaging device; its purpose is to create a well -defined image using
an elaborate pre-fabricated sub-wavelength structure on the plate's surface. The goal
for this study is to observe an a priori unknown sub-wavelength image using a near
field structure. In the past, successes (Reference 19) in retrieving images of sub
wavelength objects (such as A/20 holes) using an NSOM for radiation detection are
achieved. An NSOM is a near-field instrument, therefore, a much more desirable
detection method would involve far-field detection. To advance this goal, and to
develop a tool sometimes referred to as the FSL, we've initiated research on multi
beam multi -detector sub-wavelength holography illustrated in Figure 10.

figure 10. Tomographic Multi-Beam Multi-Detector Holography of Sub-Wavelength Objects Using
Indefinite Permittivity Medium (IPM). Incident beam(s) scatter off the sub-A object, propagate through the
1PM, and then get re-scattered into the far field by the grating with the period D. The purpose of the multi-detector
arrangement is to disentangle the k1 and kz spatial wave numbers in t he object's spectrum (shown in the left
panel). Beams A and B are phase-shifted with respect to each other.
