Hello everyone I am working on RF MEMS based phase shifters, in almost all the publications there is a mention of bragg frequency which limits the operation range of the device. However i am yet to get a single paper where proper derviation/ implications of this Bragg frequency is mentioned. I would be thankful if anyone can help me in this regard. I want details on bragg frequency . Thanks in advance Indrajit -- ******************************************************************************** * * Indrajit Paul * F-93 Student Hostel * Indian Institute of Science * Bangalore-560012 * Karnataka * India * *******************************************************************************
