HIGH POWER MICROWAVE RESEARCH
Raytheon Ktech personnel have extensive experience designing, virtually prototyping, assembling, testing and demonstrating mobile, ruggedized HPM sources. Raytheon Ktech is currently building the Directed Energy Test and Evaluation Capability (DETEC) Narrow Band Test Systems (NBTS).
E&M, PIC, HYDRODYNAMIC SIMULATION
AFRL RF-PROTEC
Raytheon Ktech uses the AFRL RF-PROTEC code to model the engagement of a high-power microwave source against a set of targets placed inside a target structure. It can simulate the effectiveness at various angles and ranges of the source with respect to the target structure. Figure 1 shows a generic configuration with a three-story building. The figure also shows a contour plot of the microwave intensity on the second floor.
ORCAD PSPICE
Raytheon Ktech uses the OrCad PSpice program to draw circuit schematics and simulate their behavior for prototyping and for assisting in analyzing experimental results. Figure 2 is an example of the complexity of a Spice circuit needed to realistically model just a single common pulsed power component.
MODELING AND SIMULATION
ELECTROMAGNETIC AND MECHANICAL/FLUID FLOW
Raytheon Ktech has extensive capabilities for carrying out numerical simulations for electromagnetic and mechanical/fluid flow problems. For electrostatic problems, Raytheon Ktech uses Electro (2D) and internally developed finite element codes (2D, 3D). For electromagnetic/full wave problems, we use both Finite Difference Time Domain (FDTD) and Finite Element Frequency Domain (FEFD) codes. The FDTD codes include Poly2dc and Poly3d for two and three dimensional problems. The FEFD codes include NEC4 and WIPL-D.
Raytheon Ktech has modeled several types of explosive generators using CTH and ALE3D hydrodynamic computer codes with the goal of developing new versions of relatively small magnetic flux compression generators (FCGs).
ICEPIC PARTICLE-IN-CELL PLASMA SIMULATION CODE
Raytheon Ktech has extensive experience with the ICEPIC particle-in-cell plasma simulation code. Our personnel use these codes for a wide range of analysis including narrow band, wide band and ultra-wide band antenna studies and modeling of High Power Microwave sources.
MICROWAVE ANTENNA SYSTEM (MAS) CODE
Raytheon Ktech developed the conceptual approach, derived all physics and authored the entirety of the Microwave Antenna System (MAS) Code, a computational tool for virtually prototyping high performance reflector/radome systems for pulsed high power microwave (HPM) sources. The MAS code is an enabling technology allowing transition of HPM sources from laboratory prototypes to fieldable systems. Optimizing analyses provided by this tool are instrumental in achieving high gain performance.
COSMOSWorks FINITE ELEMENT SYSTEM
We use our substantial capabilities in static and dynamic structural analysis with the COSMOSWorks Finite Element system to carry out detailed mechanical design and analysis for Pulsed Power Systems, High Power Microwave devices, and wide band antennas. Raytheon Ktech also has experience using COSMOSFlow Works and ALE-3D to carry out compressible and incompressible fluid dynamics simulations for several government projects.
