Switches must perform under rather dramatic conditions compared to other components and switching media are of utmost importance.

High power microwave (HPM) sources have been developed over the past few decades for many important DoD missions ranging from electronic warfare to intentional EMI to impulse radar. One important area of development for HPM devices is ballistic missile defense (BMD). HPM systems and techniques may be able to disrupt, damage, or destroy critical elements of adversary ballistic missile systems, rendering them ineffective. However, the goal is to be able to have these effects at long standoff distances, which is often difficult given the limited space available on appropriate BMD platforms, such as interceptor missiles. There are several ways to improve the standoff range of an HPM system. The first is to increase the total power on target. The second is to increase the effectiveness at a given power level by improving coupling and damage effects. ASR Corporation (ASR) has been working in conjunction with Prof. J. Scott Tyo at the University of Arizona (UA) for the past several years on the development of compact, mesoband HPM sources based on conventional source and antenna topologies. We have developed a range of prototype systems designed to fit in small volumes on mobile platforms such as UAVs. The work proposed here will take the antenna technologies further toward a finalized end product.

High power microwave (HPM) sources have been developed over the past few decades for many important DoD missions ranging from electronic warfare to intentional EMI to impulse radar. In this proposal, we describe an integrated program that seeks to develop innovative solutions based on mesoband source and antenna technology to improve the effectiveness of HPM-based BMD systems. Our research will be focused both on the sources that generate the HPM energy and the antennas that deliver it. The primary current limitation on the antenna front is the development of efficient radiators that can fit into the compact spaces available on BMD systems. To address these issues, we propose metamaterial-enhanced and metamaterial-inspired compact antenna designs that take advantage of recent advances in low power electrically small antennas for communications applications.

2011 IEEE Avionics, Fiber- Optics and Photonics Technology Conference, AVFOP 2011 | Year: 2011

On behalf of the IEEE Photonics Society we would like to welcome you to San Diego for the IEEE Avionics Fiber Optics and Photonics Conference (AVFOP 2011). AVFOP is the result of a 2004 government and industry consensus championing a standalone fiber optics and photonics conference dedicated to the field of avionics. This application-oriented conference is intended to provide a common international forum for leaders, researchers, engineers, technicians, logisticians, and instructors to convene and discuss all aspects of avionics fiber-optic component and systems technology and its future direction. Over the next three days you will be given the opportunity to meet with a wide range of commercial, defense, academic, and aerospace sector professionals engaged in the development and application of wideband digital and RF fiber-optic link, cable plant, and networking technologies. © 2011 IEEE.

Since there is no clear final configuration, ASR has chosen to contemplate a design concept to be accomplished during a potential Phase II award along with a Phase I work plan to demonstrate feasibility of the Phase II concept. ASR proposes to develop an HPM source for deployment into the MLRS M26 payload bay. Multiple, parallel FEGs will charge a single quarter wave oscillator to 100+ kV and each FEG will be fired in order to accomplish the 100+ Hz pulse repetition rate. When the oscillator is fully charged, an internal switch closes and the oscillator will begin to oscillate with the chosen antenna load to generate a wideband radiated signal.

Recent advances in electrically small antennas have been proposed for a range of communications applications. In general these antennas have wide impedance bandwidths, but low efficiency and power handling capabilities. Recently members of our team at the University of Arizona have developed a class of efficient electrically small antennas (EESAs) that we call the EZ antenna that gets around these limitations through careful design of the space-loading of the antenna. The loading strategies we have pursued are based on advances in the field of metmaterials. We have designed and built prototype systems throughout the 100 MHz"10GHz frequency rantes, but our designs have not been optimized or tested for HPM applications. In this proposal, we seek to alter the strategies proposed for low-voltage electrically small geometries and adapt them to handle high input voltages and powers.

ASR proposes to develop an HPM source for deployment into the MLRS M26 (or smaller) payload bay. Multiple, parallel FEGs will charge a single quarter wave oscillator to 100kV or more, and each FEG will be fired in order to accomplish the desired pulse repetition rates (PRR) in excess of 100 Hz. When the oscillator is fully charged, an internal switch closes and the oscillator will begin to oscillate with the chosen antenna load to generate a wideband radiated signal. A secondary prime power supply will be based on thermal batteries for those applications in which explosives are not appropriate.

The Navy has a need to control such extreme power specifications that no suitable switches exist. The Navy power specifications require us to develop a novel medium (probably a pressurized gas or liquid) that can be configured to meet the requirements and control the flow of electrical power directly. Our extensive switching expertise has allowed us to develop a series of novel test fixtures and to perform a series of preliminary experiments to explore a wide variety candidate mediums during the Phase 1 base.
