Abstract
A method for forming an electromagnetic shielding material includes causing a first portion of a matrix material to enter a target region of a magnetic field, thereby causing first ferromagnetic particles within the first portion of the matrix material to move such that first longitudinal axes of the first ferromagnetic particles become more aligned with the magnetic field. The method also includes curing the first portion of the matrix material within the target region of the magnetic field and thereafter causing a second portion of the matrix material to enter the target region of the magnetic field, thereby causing second ferromagnetic particles within the second portion of the matrix material to move such that second longitudinal axes of the second ferromagnetic particles become more aligned with the magnetic field. The method also includes curing the second portion of the matrix material within the target region of the magnetic field.
