ABSTRACT = {An	efficient	method	of	moments	(MoM)	based	on	polynomial	chaos	expansion(PCE)	is	applied	to	quickly	
calculate	 the	electromagnetic	scattering	problems.	The	 triangle	basic	 functions	are	used	 to	discretize	 the	
surface	integral	equations.	The	PCE	is	utilized	to	accelerate	the	MoM	by	constructing	a	surrogate	model	for	
univariate	and	bivariate	analysis[1].	The	mathematical	expressions	of	 the	surrogate	model	 for	the	 radar	
cross-section	 (RCS)	are	established	 by	 considering	 uncertain	 parameters	 such	as	 bistatic	angle,	incident	
frequency,	 and	 dielectric	 constant[2,3].	 By	 using	 the	 example	 of	 a	 scattering	 cylinder	 with	 analytical	
solution,	it	is	verified	that	the	MoM	accelerated	by	PCE	presents	a	considerable	advantage	in	computational	
expense	and	speed.},
