Notes 
High order vector finite element method in electromagnetics     
                                                                
The matrices came from analysis of a 9-th order microwave       
combline filter with second order (LT\QN) vector finite elements
with different mesh quality. The matrices were used as an       
example in our paper [1].                                       
                                                                
gsm_106857 - real symmetric matrix (589446 x 589446) and        
    21758924 nonzero elements. First 98577 unknowns corresponds 
    to lowest level (CT\LN) base functions.                     
                                                                
All matrices are sparse and come with right-hand-sides.
