## Abstract

This research is content study about propagation of the light on macrowaves trapeziform. This research divided become two phases. The first phase is study about propagation of the light on mathematics. This phase aim to get relations between collector lenght, collector skewness, collector wide, and refraction index collector on numerical aperture (NA). The result of this research show that the general formula of reflection for-i on solar collector organized as trapeziform is is top angle collector, and is angle formed by collector side to perpendicular line of collector axis. In the other side, general formula for calculating minimum collector length in order to the light come with certain incidence angle creeping on collector without across critis angle i) for even n (n=2,4,6,...), and for odd m (m=3,5,7,...). By using formula dan X can be got mathematical NA. After this research had done on mathematics, the next phase examined the result in a experiment. The sample for this experiment is made of PMMA. The phase this experiment divided become five phases. There are measuring PMMA absorbance, measuring PMMA reflectance, measuring PMMA refraction index, ce until ent can be got PMMA reflectance curve for wave mode TE and TM. Where as for the third experiment can be got PMMA refraction index, and for the fourth experiment can be got collector NA for every collector length variation with collector skewness angle variation 83°, 85° and 87°. Length variation that used is 5,25cm, 6cm, 6,5cm and 7cm. The result of this research is obtained result NA which much the same to with result of mathematical calculation. Keyword : Solar collector, Absorbance, Reflectance, Rrefraction Index, NA
