![]() ![]() Investigated using the CST Microwave Studio for the bi-function operation. HF-simulations with CST Microwave Studio and measurements were done. The radiation characteristics of the array are Phases of the successive unit-cells are kept the same of their locations in the The compact structure of the antenna array saves the cost and the allocation area for the terahertz communication applications. A dual-beams reflectarray/transmitarray antenna is achieved by rearranging the cell elements of the array successively.įinally, a single structure is used to work as reflectarray and transmitarrayĪntenna at the same time by rearranging the applied voltages between theĭifferent pieces of the graphene sheet using chess board arrangement. Reflectarray/ transmitarray antenna covering an area of 364 × 364 μm2 is proposed. The compact structure of the antenna array saves the cost and theĪllocation area for the terahertz communication applications. Graphene DC biasing voltage to transform the transmitting antenna to reflectingĪntenna. ![]() Of a single array structure in the THz band. Tunability of graphene conductivity introduces the bi-function characteristics Is switched between two status, reflectarray and/or transmitarray. ![]() Lens antenna in terahertz (THz) band has been investigated. It has modules for Magneto-statics, Induction, Electrokinetics, Electrostatics, Static current conduction besides the modules on thermal and stress analysis. This course also provides a general introduction to Multipactor and Corona discharge effects. The Time Domain solver is the perfect solution for broadband traveling-wave components like transmission lines and transitions, as well as highpass/lowpass filters. Throughout this course you will become familiar with the Spark3D interface and how to perform basic functions in terms of modeling, setup of simulation, and analyzing pre-/post-processing results. Reflectarray, Transmitarray, Graphene, Single/Dual-Beam Antenna, THz Applications CST Studio Suite technology provides a range of electromagnetic solvers are available for the simulation of microwave filters and components. If you dont want to use a script, then generate these points in excel and import them using 'Curves->3D Polygon->Load File'.
