The computer integrated circuitmn (IC) is inundated with electromagnetic signals. These signals are omnipresent at the device, chip, package, and board level. The length-scales vary from nanometers to centimeters. The physics also changes significantly over these length-scales. It is clear that multi-scale, multi-physics analyses are needed to understand future generation IC's.
In this paper, we will discuss two methods to tackle the low-frequency, multi-scale electromagnetics problem. First we will discuss the augmented electric field integral equation (AEFIE), and then, we will discuss the equivalence principle algorithm (EPA). The AEFIE allows the solution of such problems without the need to perform a loop search of a complex structure. The EPA allows the separation...
A linear sensor array can be used to acquire images by push-broom scan mode. Usually the sensor elements of a sensor are square. However, in some special applications, the rectangular sensor elements are used, in which the images are blurred in the scan direction.The blur process can be modeled as a kind of smooth in the scan direction, like the motion blur. The paper discusses how to build the mathematical...
