ince many applications rely on the knowledge of the electromagnetic
material properties of ferrites, such as ferrite phase shifters, this paper
presents an algorithm for characterizing ferrite materials in a single
frequency using a rectangular waveguide system. In this method, the
extraction of ferrite parameters is implemented through minimizing the
difference between the measured data and the results from modal
analysis of the system. The main advantage of this method compared to
the other ones is that the proposed method only needs the amplitude of
the reflection and transmission coefficients to estimate the parameters of
ferrite materials. This makes the implementation easy and eliminates the
problems associated with phase calibrations and measurements. This
validation is achieved by simulation and experimental tests. The
proposed algorithm is validated by characterizing YIG and SL-470

Journal of Electrical and Computer Engineering Innovations (JECEI) welcomes letters to the editor for the post-publication discussions and corrections which allows debate post publication on its site, through the Letters to Editor. Letters pertaining to manuscript published in JECEI should be sent to the editorial office of JECEI within three months of either online publication or before printed publication, except for critiques of original research. Following points are to be considering before sending the letters (comments) to the editor.

[1] Letters that include statements of statistics, facts, research, or theories should include appropriate references, although more than three are discouraged.

[2] Letters that are personal attacks on an author rather than thoughtful criticism of the author’s ideas will not be considered for publication.

[3] Letters can be no more than 300 words in length.

[4] Letter writers should include a statement at the beginning of the letter stating that it is being submitted either for publication or not.

[5] Anonymous letters will not be considered.

[6] Letter writers must include their city and state of residence or work.

[7] Letters will be edited for clarity and length.
