Research into Rydberg atoms as traceable microwave sensors is of growing interest to theatomic physics and microwave electrometry communities. Atomic vapor contained in glass cells can make accurate over-the-air electric field measurements from frequencies ranging from DC to THz. The growing applications and interest in this field requires a deeper look at potential sources of error when using Rydberg atomic vapor as a microwave measurement device. This thesis will discuss using Rydberg atoms as microwave sensors in the capacity of power measurement, angle of arrival, DC measurement, and multi-level excitation schemes. The aim of this work is to combine a microwave engineering perspective with atomic physics modeling and experimentation to predict Rydberg atom response in the presence of microwave field variations. The glass vapor cell commonly used to contain atomic vapor acts as a dielectric load to microwave signals. The microwave response inside of the vapor cell is difficult to predict because of the large variance in the microwave electrical permittivity of Pyrex glass, which depends on the unique cooling rate of the material after being blown into shape. Microwave modeling helps to predict how the fields are distributed inside of the glass cavity, and combining these field distribution models with atomic simulation allows for better understanding of sources of error in microwave measurements using Rydberg atoms.
