They are not for integrated simulations and it is hard to improve their solution algorism.
In its original, rudimentary form, algorithms, known as algorism, was regarded as rules for computing calculations and performing arithmetic with Hindu-Arabic numerals.
Firstly the element in the 3D AET is expressed in three dimensions different from the one of 2D AET, where the most different point between 2D AET and 3D AET is the ray-trace technique in the algorism.
We proved that the amplitude-comparison DF's DF accuracy has been improved by 60% through the improved algorism suggested in the paper, and we expect that the device size can be reduced below a half size of a device that has the same performance.
However, this algorism was not strong in texture enhancement.
