Microwave simulation experiments of laser-produced coronal plasma are presented. Extensive studies of hot electron heatings due to resonance absorption of moderate-intensity ({ital v}{sub 0}/{ital v}{sub {ital e}} {lt} 0.3, or {ital I}{lambda}{sup 2}/{ital T}{sub {ital e}} {lt} 3 {times} 10{sup 14} W/cm{sup 2} {mu}m{sup 2}/keV), {ital p}-polarized microwaves have been made. A simple theory is developed based on warm plasma wave breaking to explain the experimental results. The experiments agree well with the theory and electromagnetic computer simulation calculations. Therefore, it is shown that the microwave experimental results of resonance absorption scale to laser parameters.
