Introduction

This chapter provides a general overview of simulation-driven design of high-frequency structures, the associated challenges, and the popular ways of their mitigation. Widely used optimization and modeling techniques are briefly mentioned, both data-driven (approximation) and physics-based ones. The concept of response feature technology is outlined, as well as a brief discussion of its properties and applicability. The overall outline of the book topics and scope is also elaborated on along with the book structure.
