• Full-Wave Electromagnetic (EM) Simulation 

Ansys HFSS
  Throughout my Master’s program, Ansys HFSS has been my primary tool for high-precision microwave component design. I have leveraged its FEM solver to develop a Ka-band 4x1 beamformer and a Ku-band 8x1 Amplifying Reconfigurable Intelligent Surface (A-RIS). My work involves synthesizing various patch antenna architectures—including proximity, direct, and probe-fed configurations in single-layer or stacked formats—while optimizing microstrip and GCPW interconnects. To meet stringent insertion loss and isolation goals, I specialized in designing vertical transitions and implementing via-fencing to suppress surface and leaky waves.

CST Studio Suite
  I complement this with CST Studio Suite for the simulation of electrically large systems and periodic structures. Leveraging the Transient Solver, I have modeled bulky architectures such as large-scale RIS and reflectarrays where time-domain efficiency is critical. Furthermore, through my academic coursework, I have developed expertise in the design of impedance surfaces and metamaterial atoms, including SRR and cELC resonators. Within this framework, I am proficient in executing S-parameter retrieval and applying Transformation Optics (TO) principles to engineer gradient-index media.

Sonnet
  I also utilized Sonnet 2.5D for high-accuracy circuit tape-outs, leveraging its shielded domain to precisely characterize microstrip, GCPW, and crossover structures. By accounting for enclosure effects and coupling prior to fabrication, I ensured rigorous physical verification for successful hardware implementation.

• Circuit Simulations

Keysight ADS
  Keysight ADS has been a primary tool for both high-level system analysis and detailed circuit design throughout my research. I leveraged its capabilities to perform rigorous stability analysis for active components, including 1-port reflection amplifiers and my A-RIS project, while applying network analysis to investigate advanced physical phenomena like Exceptional Points (EP) and Coherent Perfect Absorption (CPA) during my visiting program at UCSD. Furthermore, I have extensive experience in the full design cycle of passive and active components, including crossovers, hybrid couplers, filters, and LNAs.
