【 摘 要 】

Theoretical and experimental study of light propagation in acrylic triangle waveguides has been studied theoretically and experimentally aimed to obtain a light cone which can tunnel and bring the light to a certain place. Numerical aperture of light cones which have a length of 7 cm but different cross-section area have been measured using he-Ne laser (λ=632 nm) and the results were compared to those obtained theoretically and no significant different was observed.
