Calculation results suggest that the proper range of phase shift for general application is about from 0.5 to 2.0 rad for both the fixed and linear phase shift errors.
Only 180° shifts of the radiofrequency phase are used, and the performance is remarkably insensitive to the exact setting of this phase shift.
This concept is able to provide any desirable phase shift.
The study also showed that the operating temperature plays an important role in achieving the optimum phase shift for microwave applications.
These results can provide guidelines for fabricating any phase shift value FBGs.

What is solar radio burst?
5 answers
Solar radio bursts (SRBs) are brief periods of enhanced radio emission from the Sun that contain information about the plasma where the emission originates. They can provide critical information about space weather events such as coronal mass ejections (CMEs). SRBs are the result of particle acceleration by shock waves in the solar corona and interplanetary medium, created by solar eruptions involving CMEs traveling at super-alfvenic speeds. They are generated by beams of energetic electrons traveling along open magnetic field lines through the corona and into interplanetary space. SRBs serve as ground observed data to provide early notice of incoming solar storm disturbances and can be used to monitor the current progress of solar cycles and predict the intensity of associated space weather phenomena. Solar flares are known to produce impulsive solar radio emission, which is classified as SRBs.
