Maxwell – Hertz - Hulsmeyer
• Maxwell (1864) : theory (predictions) of
electromagnetic field
• Hertz (1885-88) : experimental verification of
Maxwell’s equations
• Demonstration that radio waves behave the same
as light, except for frequency difference
• Demonstrated radio wave reflection from metallic
objects
• Demonstrated radio wave refraction by dielectric
prism
• Hulsmeyer (1904) invention of Radar
