Abstract Examining the effectiveness of microwave
energy for control of the Colorado potato beetle (CPB) in potato crops begins
with an investigation of the dielectric properties of the insect and plant.
This paper presents the measured complex permittivity of the CPB and potato
plant over the frequency range 100 MHz to 26.5 GHz obtained using coaxial
probes and an automatic network analyzer. Specific measurements include the
beetle prothorax, thorax, and abdomen as well as the plant leaflet, petiole
and stem. An RMS error of less than 0.79 is obtained for both the real and
imaginary permittivity over the band for measurements of Key Words: Colorado potato beetle, Potato plant, Complex
permittivity, Coaxial probe, Microwave, Measurement. |
