Wenhao Peng is pursuing his doctoral studies with the Electrical Engineering and Computer Science department at the University of Michigan after his completion of the (UM-SJTU) dual (B.S.) degree program (ECE and EE) in 2018. Wenhao is currently a PhD candidate in the RADLAB. His current research interests include designing and modeling acoustic wave resonators driven by thin-film piezoelectric and ferroelectric materials for use in passive radio filters, and developing fabrication technologies for such resonators whose operation frequencies are up to 50 GHz. He is also 75% (21 credits completed, 3 crecits in progress, 6 remaining credits to study) towards the completion of a Mechanical Engineering Master's degree, with an emphasis on dynamics and vibrations and structural acoustics.

Teaching Assistance
University of Michigan
EECS 411: Microwave Circuits I Lead lab sessions. FA2019, FA2020, FA2021. Introduction to the Microwave instruments and CAD tools. Coupler, amplifier, and filter measurements. Also give office hours to answer questions regarding pre/post-labs, the major design experience project, and homework, which cover transmission lines, impedance matching, S-Parameters, high gain and low noise amplifier designs, noise and nonlinearity, LC ladder-type filters, a few mixer designs, and Microwave resonators.
EECS 312: Digital Integrated Circuits Lead discussion sessions and help with the CAD tools. WN2021, FA2022. Starting with the device physics of MOSFET, a circuit representation of NMOS and PMOS is introduced. Implementation of static and dynamic logic gates using MOSFETs, and delay and energy considerations are taught. Digital circuits at a higher level, such as the adder, elements for sequential logic, timing constraints, and several memory elements are then introduced.
EECS 215: Introduction to Electronic Circuits WN2022, WN2023, FA2023. Although the circuits themselves were basic, the skills and knowledge he acquired during his education in electrical engineering helped a lot when assisting students experiencing issues with the labs.

VP 160: Honors Physics I Give recitation classes using a deck of slides he composed in LaTeX with emphasis on problem solving skills. SU2016, SU2018. Kinematics, inertial frames of reference, Newtonian mechanics, oscillations with linear drag, non-inertial frames of reference, work and energy, elements of Lagrangian mechanics, collision and momentum, angular momentum, rigid body dynamics, equilibrium and elasticity, fluid mechanics, and gravitation. He wrote a small program in C++ and visualized the trajectory of several objects in a kinematic problem using OpenGL using the template from VG101, and the following animation is a collection of the snapshot from that visualization. The second image shows his creative thinking in solving one simple problem using three topics (non inertial frame of reference, work and energy, and elements of Lagrangian Mechanics) covered in the second midterm exam for VP160. The third image shows how Wenhao explains the Eigenvalue Problem to freshmen students who are studying this for the first time before their maths classes get to this topic.

VC 210: Chemistry Give recitation classes with emphasis on key concepts from the textbook. FA2015. Structures of atoms and compounds, stoichiometry, thermochemistry, electron configurations of atoms, chemical equilibrium, chemical bonding, reaction rates, chemical thermodynamics, and electrochemistry. The first image shows Wenhao explaining the wave-like properties and particle-like properties of light. The second image shows Wenhao explaining the rate law for chemical reactions in the final review session. The third image shows Wenhao explaining Gibbs free energy and its relation to which direction of the chemical reaction is spontaneous.
