We review the space-mapping (SM) technique and the SM-based surrogate (modeling)
concept and their applications in engineering design optimization. For the first time, we …

In this paper, we outline the historical evolution of RF and microwave design optimization
and envisage imminent and future challenges that will be addressed by the next generation …

This paper presents a comprehensive approach to engineering design optimization
exploiting space mapping (SM). The algorithms employ input SM and a new generalization …

We introduce the idea of implicit space mapping (ISM) and show how it relates to the well-
established (explicit) space mapping between coarse and fine device models. Through …

The most widely used space mapping approach to efficient design optimization is the
aggressive space mapping (ASM) algorithm. My purpose here is to present both a historical …

A new computer-aided design (CAD) method for automated enhancement of nonlinear
device models is presented, advancing the concept of Neuro-space mapping (Neuro-SM). It …

This paper outlines the early history of optimization technology for the design of microwave
circuits—a personal journey filled with aspirations, academic contributions, and commercial …

Mesh space mapping (MSM) is widely recognized as a popular surrogate-based
optimization approach for expediting electromagnetic (EM) design, particularly in cases …

Parametric modeling of electromagnetic (EM) behaviors has become important for EM
design optimizations of microwave components. This paper provides an overview of recent …

We present a significant improvement to the novel implicit space mapping (ISM) concept for
EM-based microwave modeling and design. ISM calibrates a suitable coarse (surrogate) …
