The proposed antenna is suitable to operate in C-band, ISM/WLAN/Military application, mid-band 5G, maritime radio navigation, X-band satellite communication, and public safety.
The simulated results are in good agreement with measured ones. Moreover, as an excellent switch, the ON state transmittance is one order of magnitude higher than the OFF-state transmittance. The system is simulated using CST Microwave Studio, and a prototype is fabricated to verify the results. Furthermore, the results also show that when martensitic transformation occurs, the terahertz wave transmission can be tuned from 0.78 to 0.04 at 0.47 THz. And the resonant frequency of the band-stop filter achieves a dynamic modulation range up to 0.56 THz. CST MICROWAVE STUDIO provides a link between MATLAB ® and CST MWSs VBA macro language. The product offers users shorter development cycles through virtual prototyping before physical trials and optimization instead of experimentation.
Through the seamless integration in CST’s design environment, multi-physics simulation has become straightforward. It features a mechanical stress solver as well as a stationary and a transient thermal solver, both of which are capable of considering the bioheat equation. The frequencies of both LC and dipolar resonances can be dynamically tuned to the desired operating frequencies by driving the martensitic transformation. CST MWS specializes in providing fast and accurate 3D electromagnetic simulation of high frequency problems. CST MPHYSICS STUDIO is a part of CST STUDIO SUITE. Based on the novel NiTi metamaterials, inductance-capacitance (LC) resonance and dipole resonance are used simultaneously for the terahertz filter, and an excellent dual-band filter is obtained. The influence and mechanism of the shape deformation and conductivity changes before and after martensitic transformation on the electromagnetic response are systematically investigated and revealed. known as the Bulls Eye antenna 49, which consist of several concentric. In this work, NiTi films are innovatively introduced into the design, and multifunctional and dynamically tunable terahertz metamaterials are proposed. Chapter 4 consists of a short introduction to CST microwave studio software. In the terahertz (THz) fields, a crucial point of restricting its development and application is the lack of dynamic and multifunctional materials.
