EFFICIENT ANALYSIS OF ELECTROMAGNETIC FIELDS FOR DESIGNING NANOSCALE ANTENNAS BY USING A BOUNDARY INTEGRAL EQUATION METHOD WITH FAST INVERSE LAPLACE TRANSFORM

Abstract

In this paper, we investigate electromagnetic problems for nanoscale antennas by using a boundary integral equation method with fast inverse Laplace transform. The antennas are designed for realizing ultra-fast and high-density magnetic recording. Characteristics of nanoscale antennas are discussed in terms of eigenmodes and time domain responses of electric fields. Our computational method is highly efficient and the computational cost can be reduced by selecting coarse time-step size and performing parallel computation.
