Formed MARIETTA SCIENTIFIC, Inc. to provide Radar Cross Section engineering services and software development. At DENMAR, Inc., Radar Cross Section Engineering Support Services, established the Atlanta Office. Provides training, analytical, project, measurement, and materials analysis support to industry and government. Has developed a three day Design Oriented Radar Cross Section short course and specialized Method of Moments codes for 3-D patches, bodies of revolution, wires, and 2-D R card geometries. Recent co-author of a chapter in Radar Reflectivity Measurements. At the Georgia Tech Research Institute lectures for the Radar Cross Section Reduction Short Course and has aided in course reorganization. At LockheedGeorgia Possum Works, was Engineering Program Manager for Low Observables. Organized, hired, and trained a staff of RCS engineers. Responsible for Internal and Contract Research and Development (IRAD and CRAD) Programs in LO; for intercompany work; for LO Technology Development for program applications; and for staffing programs with LO engineers. The LO Group was organized with groups for: Analysis, Test, Materials, and Projects. Is the second of three authors of Radar Cross Section, published by Artech, 1985 and the second edition in 1993. At Georgia Tech, was project director in the area of general electromagnetic modeling and RCS measurements/data reduction. Has been one of the three principal authors and lecturers of a radar cross section training course. Has developed unique numerical methods to model the magnetic fields of Naval vessels. Lectured on "Factors External to the Radar," in the Principles of Modern Radar short course; and also "Electric, Magnetic, and Dielectric Static Field Models," in the Electromagnetic Signatures short course. At the McDonnell Douglas Research Laboratory, worked on techniques and methods for analytically modeling electromagnetic behavior of complex shapes and structures. Has formulated a strong coupling analysis for computer codes based on the method of moments, and developed electrostatic codes for analysis of multiple conductors described by potential or net charge immersed in an external electric field. From 1974 to 1977, was associated with the Gas Dynamics Laboratory and developed computer codes for the analysis of swirling, turbulent radiative arc heater flow fields. These codes involved numerical techniques for solving coupled systems of nonlinear, parabolic, partial differential equations. From 1971 to 1974, was associated with the Electronic Systems Technology Group of McDonnell Aircraft, investigating the interaction of lightning and other electrostatic phenomena with aircraft and for investigating electromagnetic shielding properties of advanced graphite and boron epoxy composite materials and structures. Work at McDonnell from 1966 to 1968 involved the design and diagnostic of radio frequency generated plasmas. Graduate work at St. Louis University was in plasma physics. Dissertation topic was "Electrostatic Probes in Collisionless Plasmas," an experimental investigation of spherical and cylindrical electrostatic probe responses.
Numerical electromagnetic modeling; resonant region radar cross section analysis; antenna analysis.
