liability of existing materials. Description: Vacuum-grade high purity copper
and copper-nickel alloys such as Monel
and cupronickel (ref 1, 2, 3) are highly
desirable in MWT manufacturing processes because they are corrosion resistant, often stronger than steel, have a
low coefficient of thermal expansion,
and can be welded and brazed, both to
other metals and to metallized ceramics. However, these alloys are considered "niche" market materials and are
therefore expensive and increasingly
only available from foreign suppliers.
Alternatives are sought to improve existing manufacturing techniques for
MWT relevant metal alloys and/or to develop new materials suitable to replace
existing vacuum-grade materials while
maintaining MWT compatible characteristics such as coefficients of expansion, manufacturability and thermal
conductivity required by the industry.
This effort will develop a concept, and
demonstrate the feasibility of (through
material testing and analytical modeling), for providing high purity materials for MWT applications that meet Navy

needs; develop prototype materials and
processes; and provide for evaluation of
the effectiveness of MWTs incorporating the materials in an operationally
relevant environment. Point of contact:

Topic N14A-T021: Affordable 3D Printed Phased Arrays. Objective: To develop
a low cost phased array technology enabled by 3D direct digital fabrication. Description: The promise of 3D printing to
manufacture a phased array antenna can
dramatically reduce cost and enhance the
mechanical, electrical and radio frequency (RF) performance through high precision dense integration. A multifunction
3D layer can include low power functions
such as phase shifting or true time delay, gain control, switching, low power
amplification, filtering, interconnectivity, thermal management and mechanical packaging. This effort will design
and model key elements of a 3D printing technology approach for fabrication,
testing, and cost analysis of a steerable
multi-element array, including a method
to incorporate non-printable, large-sig-

alter the EM wavefront of the transmitted signal and obscure the location of
broadcast platforms. A device is needed
that will allow for the accurate and efficient replication of advanced adversary
capabilities; making warfighters battle
ready. This effort will conduct computer
simulation of developed spectrum monitoring method for advanced communication, evaluate modern EW methods
using computer simulations; develop
and simulate sequence discovery procedures for common communication
waveforms and build a prototype that
can accommodate most common military communication standards, employing only standard tools and languages;
and develop limited rate initial production of the device. Point of contact: Arje
