By the method of electril charge projection the expression of charge density and field intensity on midperpendicular plane on a conductive plate are given.
For the hair, Andre might use varying sizes and colors of stacking bricks, thin plates, and slanted, single, and square bricks to create a textured effect.
This is made possible through something called a lenticular lens – a corrugated sheet in which each ridge is made up of a convex – or outward-curving – lens.
A team led by Urszula Stachewicz at AGH University of Krakow in Poland found that the sheet could be made even more productive by changing the way in which its polymer threads were manufactured.
