kuvamenetelmien
The term kuvamenetelmät, translated as image methods or method of images, refers to a class of analytic techniques used primarily in physics and engineering to solve boundary value problems. The method was first formulated in the mid‐nineteenth century by the physicist Lord Kelvin and later refined by J. J. Thomson. Its core idea is to replace the influence of complex boundaries with fictitious sources (often called image charges, points, or mirrors) placed in a extended region such that the combined potential field exactly satisfies the required boundary conditions.
In electrostatics the method is most commonly applied to conductors and dielectrics. By placing appropriately signed
The principal advantage of kuvamenetelmät is that they reduce a problem that would normally require solving
Despite its age, the method of images continues to appear in modern textbook analyses and in the
