Research Interests:

• Geometric and visual methods of solving engineering equations.
  • Geometric Synthesis of Electrical Circuits:
    Note: These techniques were known to industrial engineers in the early 20th century, such as Charles Steinmetz (1865-1923) of the General Electric Company, and Harry Nyquist (1889-1976) of AT&T. However, these techniques seem to have disappeared from the modern academic curricula, textbooks and publications on circuit analysis and synthesis.
    • Geometric Visualizations:
      • Visualizing Parallel Resistors, with Applet
      • Visualizing Resistors in Parallel with Reactances in the Z-plane (parallel phasors), with Applet
      • Visualizing Parallel Reactances in the Z-plane.
      • Geometric Method of solving the First Order High Pass Filter.

    • Geometric Circuit Synthesis in the Z-plane:
      • LC Circuit for matching transmission lines. An example.

  • Visualizing solutions to n-th degree algebraic equations using right-angle geometric paths.
