Mostly Printed Field Characterization System (MPFCS)

#Mostly Printed Field Characterization System

The Mostly Printed Field Characterization System (MPFCS) is a CNC-based scanning system for devices' electric and magnetic fields. Given a device, it creates a 3D point cloud of the fields resulting from a EM Transmitter (e.g. a complex WPT Coil) using a [field probe](https://beehive-electronics.com/probes.html) mounted to the [MPCNC](https://docs.v1engineering.com/mpcnc/intro/)'s end effector. This end effector contains two stepper motors that allow tilt through 90deg and pan through 180deg down to 0.05deg accuracy. Additionally the above field probe can be replaced with a receiving coil to capture S21 data for characterizing the transfer between a transmitter and receiver. The system was built almost entirely of 3D printed and off-the-shelf parts.

Although remarkably reconfigurable, our main use case is for characterizing wireless power systems. The MPFCS acts as a design tool for systems with fields that are too complex to feasibl
