Research on reflection and transmission characteristics of electromagnetic wave to corn leaf

In this paper, the coefficient of reflection and transmission of electromagnetic wave on corn leaf are computed under room temperature. The relationship is given when the thicknesses of leaves are 0.5 mm, 1.0 mm and 1.5 mm and the proportion of water in the weight are 0.25, 0.5 and 0.68. The rules are concluded that there would be longer period and easier expression of the two coefficients on the incident electromagnetic wave, when leaf is thicker or the proportion of water is heavier. On the contrary, opposite results are obtained. There are less affection that the changes of the leaves thickness on the maxima of the reflectance coefficient and the average of the transmission coefficient, but add the proportion of water can less increase maxima of reflect coefficient, at the same time, the average of the transmission coefficient will come down.
