AB  - The paper presents a novel fast calculation method for broadband Electromagnetic Scattering analysis. In 
this work, the isogeometric boundary element method is used to solve Helmholtz equations for the 
electromagnetic scattering problems. The non-uniform rational B-splines are employed to construct 
structural geometries and discretize electric and magnetic field integral equations [1,2]. To avoid timeconsuming multi-frequency calculations, the series expansion method is used to decouple the frequencydependent terms from the integrand in the boundary element method [3,4]. The second-order Arnoldi 
(SOAR) method is applied to construct a reduced-order model that retains the essential structures and key 
properties of the original model for large-scale problems [5-7]. Several numerical examples are presented 
to demonstrate the correctness and effectiveness of the proposed algorithms.
