Electromagnetic (EM) Logging While Drilling (LWD) plays an increasingly significant role in oil and gas exploration and development. Fast and accurate simulation of EM LWD is essential for optimizing ...

In numerous physical and biological systems, differential equations with parameters are commonly used to model specific behaviors or phenomena. These parameters frequently represent physical ...

This chapter discusses in detail the basic principles and formulations of the full‐vectorial finite‐difference time domain (FDTD) method. It presents the basic idea of the FDTD method to solve Maxwell ...

Abstract: In this letter, a 2-D parameter-optimized spatial finite-difference temporal differential (SFDTD) method is presented, referred to as the PO-SFDTD method. First, the dispersion ...

A new approach in the finite difference framework is developed, which consists of three steps: choosing the dimension of the local approximation subspace, constructing a vector basis for this subspace ...

The finite difference method is a numerical technique that approximates derivatives with finite differences. This methodology can be used to solve the heat equation. A strong overview of this ...
