This book discusses response feature technology and its applications to modeling, optimization, and computer-aided design of high-frequency structures including antenna and microwave components. By exploring the specific structure of the system outputs, feature-based approaches facilitate simulation-driven design procedures, both in terms of improving their computational efficiency and reliability. These benefits are associated with the weakly nonlinear relationship between feature point coordinates and design variables, which—in the context of optimization—leads to inherent regularization of the objective functions. The book provides an overview of the subject, a definition and extraction of characteristic points, and feature-based design problem reformulation. It also outlines a number of numerical algorithms developed to handle local, global, and multi-criterial design, surrogate modeling, as well as uncertainty quantification. The discussed frameworks are extensively illustrated using examples of real microwave and antenna structures, along with numerous design cases. Introductory material on simulation-driven design, numerical optimization, as well as behavioral and physics-based surrogate modeling is also included. The book will be useful for readers working in the area of high-frequency electronics, including microwave engineering, antenna design, microwave photonics, magnetism and especially those who utilize electromagnetic (EM) simulation models in their daily routines.

Ganglion cell responses were recorded with microelectrodes from the intact eye to focused spots and annuli of light delivered by a dual-beam ophthalmoscope. Only concentrically organized circular receptive fields were analysed. Thresholds for optimal center and surround stimuli were approximately equal, as were the latencies of on-responses from the center and surround. With whole-field stimulation center-dominance was a function of light intensity. Off-responses and center-surround interaction were observed with brief flashes (5 msec, 10 msec). With increases of flash duration the duration of the on-response did not increase by the full increment of the flash until the flashes were 50 to 80 msec. At high-flash intensities the on-response extended into the off-period and the off-response weakened and disappeared; it occurred with both on-excitation and on-inhibition and for the responses of both center and surround. These intensity effects were also studied in an intracellular recording; at high intensities, the rate of repolarization of the postsynaptic potential decreased, and the latency of repolarization was delayed.
