High-resolution Measurement of Refractive Index Based on Resonant Tunneling Effect

High - Resolution 3 - D Refractive Index Imaging

This thesis presents a theory of 3-D imaging in partially coherent light under a non-paraxial condition. The transmission cross-coefficient (TCC) has been used to characterize partially coherent imaging in a 2D and 3-D paraxial model. It is shown that the 3-D TCC under the non-paraxial condition is an overlap integral of three hemispheres or 3-D pupil functions. By an inspection of the overlap ...

Resonant Negative Refractive Index Metamaterials

Macroscopic measurement of resonant magnetization tunneling in high-spin molecules.

We report the observation of steps at regular intervals of magnetic field in the hysteresis loop of a macroscopic sample of oriented Mn12O12(CH3COO)16(H2O)4 crystals. The magnetic relaxation rate increases substantially when the field is tuned to a step. We propose that these effects are manifestations of thermally assisted, field-tuned resonant tunneling between quantum spin states, and attrib...

Refractive Index Measurement of Liquids Based on Microstructured Optical Fibers

This review is focused on microstructured optical fiber sensors developed in recent years for liquid RI sensing. The review is divided into three parts: the first section introduces a general view of the most relevant refractometric sensors that have been reported over the last thirty years. Section 2 discusses several microstructured optical fiber designs, namely, suspended-core fiber, photoni...

the effect of explicit instruction of metacognitive strategies on reading comprehension among iranian high school students

the present study seeks to determine the effect of explicit instruction of metacognitive strategies on iranian high school students’ reading comprehension ability. it also attempts to investigate the relationship between the learners reading comprehension and metacognitive strategies. furthermore, the study investigates whether iranian efl female high school students are high, medium, or low me...
