We develop and apply an optimization method to design unidirectional invisibility cloaks. Our is based on minimizing the forward scattering amplitude of cloaked object which, by optical theorem, equivalent total cross section. The use theorem circumvents need evaluate integrate over angle at each iteration, thus provides a simpler, more computationally efficient objective function optimize stru...

In this study a new approach to inverse design is presented that draws on the multi-functionality of nanomaterials and uses sets properties predict unique nanoparticle structure. This involves multi-target regression precursory forward structure/property prediction focus model most important characteristics before inverting problem simultaneously predicting multiple structural features single n...

Stripe patterns are ubiquitous in nature and everyday life. While the synthesis of these has been thoroughly studied literature, their potential to control mechanics structured materials remains largely unexplored. In this work, we introduce Differentiable Patterns---a computational approach for automated design physical surfaces with stripe-shaped bi-material distributions. Our method builds o...

Distributed Bragg Reflectors are optical structures capable of manipulating light behaviour, which formed by stacking layers thin-film materials. The inverse design such is desirable, but not straightforward using conventional numerical methods. This study explores the application Deep Learning to a six-layer system, through implementation Tandem Neural Network. challenge split into three secti...

Abstract Tunable mode converter is a key component of channel switching and routing for optical communication system by adopting mode-division multiplexing. Traditional hardly implements high-order conversion dynamic tunability simultaneously. In this study, we design tunable filled with liquid crystal, which can convert fundamental into multiple modes (TE 0 , TE 1 2 ) good performance low intr...

This paper presents the design of a novel quadruped robot. The proposed design is characterized by a simple, modular design, and easy interfacing capabilities. The robot is built mostly from off-the-shelf components. The design includes four 3-DOF legs, the robot body and its electronics. The proposed robot is able to traverse rough terrain while carrying additional payloads. Such payloads can ...
