Group Polarization

Group Polarization

Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Dielectric Polarization in a Capacitor

Dielectric Polarization in a Capacitor

The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, dielectrics can be of two types: polar and nonpolar. In a polar dielectric, the positive and negative charges in the molecules are separated by a distance and hence have a permanent dipole moment. In contrast, no such charge separation exists in a nonpolar dielectric, however the nonpolar molecules get polarized in the presence of an external electric...

Energy Stored In A Coaxial Cable

Energy Stored In A Coaxial Cable

A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that prevents signal interference, and a plastic layer that encases the entire assembly.
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic field inside...

Background:

Polarization-maintaining single-mode fibers are crucial for advanced sensing technologies like acoustooptic sensors and fiber gyroscopes.
Developing fibers with enhanced polarization maintenance is key to improving sensor performance and reliability.

Purpose of the Study:

To develop and evaluate two types of polarization-maintaining single-mode fibers: stress-induced birefringence and elliptical core.
To compare these fiber types based on critical performance metrics including core dimension, numerical aperture, attenuation, and beat length.

Main Methods:

Fabrication and characterization of stress-induced birefringence and elliptical core polarization-maintaining single-mode fibers.
Comparative analysis of key optical and physical properties: core dimension, numerical aperture, attenuation, and beat length.

Main Results:

Stress-induced birefringence fibers exhibited lower attenuation compared to elliptical core fibers.
The stress-induced birefringence fibers also possessed a larger core diameter than their elliptical core counterparts.
Beat length, a measure of polarization maintenance, was evaluated for both fiber types.

Conclusions:

Stress-induced birefringence fibers offer advantages in terms of lower attenuation and larger core dimensions.
These characteristics suggest that stress-induced birefringence fibers may be more suitable for applications requiring high polarization maintenance and reduced signal loss.
