the rotman lens, introduced in the 1960s, constitutes one of the most common and cost effective designs for bfns and is commonly utilized to enable multibeam phased array system9 and wide band operation, thanks to its implementation of true timedelays10.
لنز rotman که در دهه 1960 معرفی شد، یکی از رایج ترین و مقرون به صرفه ترین طرح ها برای bbfn ها را تشکیل می دهد و معمولا برای فعال کردن سیستم ارایه چند فازی system9 و عملیات باند گسترده، به لطف اجرای timedelays10 واقعی استفاده می شود.

application of nano/micro structures has become popular in a wide range of advanced engineering systems in recent years. for a better insight, this paper presents an intensive numerical study on the static and dynamic responses of smart functionally graded microplates with graphene platelets (gpls) reinforcement under concurrently mechanical and electrical loads. to this end, a powerful and effective numerical model based on refined plate theory (rpt), modified couple stress theory (mcst) and nurbs-based isogeometric analysis (iga) is introduced to predict the complex behaviors of small-scale structures. wherein, the mcst containing only one material length scale parameter is utilized to capture the size-dependent effects while the four-variable rpt-based iga approach is exploited to describe the displacement field. the host microplate can be constituted by four different gpls dispersions and integrated with two symmetric piezoelectric layers. a closed-loop control procedure based on displacement and velocity feedback gains is employed to actively control the static and dynamic responses of smart small-scale structures, which takes into account the structural damping effect. several numerical examples are performed to examine the influence of some key parameters such as geometry, material length scale parameter, boundary condition, dynamic load, input electrical voltage as well as weight fraction and distribution of gpls. 1. introduction with rapid technological development, the usage of nano/micro structures has become more popular in numerous engineering areas such as atomic force microscopes, micro-sensors/actuators, nanoelectromechanical devices, bio-engineering [1,2]. this trend has also created new challenges for worldwide researchers in modeling design as well as their behavior analysis under different conditions. furthermore, beam/plate-like structures integrated with piezoelectric patches have been commonly employed in micro- and nano-scale devices and systems for a wide range of mechanical, civil, structural applications [3,4]. an intensive analysis of such intriguing structures, therefore, is of great importance. for a better insight, in this study, we report an active control for static bending and dynamic behaviors of functionally graded (fg) microplates reinforced by gpls and integrated with piezoelectric layers. 1.1. related works as known as reinforcement constituents embedded into the matrix phase, carbon nanotubes (cnts) [5] and graphene platelets (gpls) ∗ corresponding author. e-mail addresses: nguyennamkt.2311@gmail.com (n.v. nguyen), jhlee@sejong.ac.kr (j. lee).
با توسعه سریع فناوری، استفاده از ساختارهای نانو/میکرو در بسیاری از زمینه‌های مهندسی مانند میکروسکوپ‌های نیروی اتمی، حسگرها/محرک‌های میکرو، دستگاه‌های الکترومکانیکی نانو، مهندسی زیستی محبوب‌تر شده است [1،2]. این روند همچنین چالش های جدیدی را برای محققان جهانی در طراحی مدل سازی و همچنین تحلیل رفتار آنها در شرایط مختلف ایجاد کرده است.
