The difference of two squares can be factorised into brackets using the method above for factorising quadratics. Factorise \(x^2 - 4\). Quadratics can be factorised into the form \((x+a)(x+b)\). \(x^2 ...

A new single-source integral equation is proposed for the solution of electromagnetic wave scattering problems. The traditional volume electric field integral equation is reduced to the new ...
