| Sumario: | The development and progress in fiber optic sensors (SFO) is due to the unique advantages they have over solid-state sensors, their main advantages are: immunity to electromagnetic interference, high sensitivity and possibility of distributed sensing, so they have found applications in a variety of fields because most of the physical and chemical variables can be monitored with SFO. One of the main detection mechanisms is the absorption of evanescent waves, so it is important to know the parameters that determine the behavior of this in SFOs. In this work we present the mathematical modeling and simulation to determine the parameters such as evanescent wave absorption and penetration depth. According to the numerical results, an evanescent wave absorption of 0.2x10-3 ua and a penetration depth of 2 µm were obtained |
