It is equipped with radio-frequency function generators, spectrum and network analyzers, standard gain horn antennas, attenuators and phase shifters, PCB milling and etching stations, a reflow oven and a SMT soldering station, and a specialized 8-core server for simulation purposes. The lab was funded partially by the School of Science and Technology start-up funds in addition to generous donations by KeySight Technologies, Inc. Members of the eel are investigating technical topics including metasurface design and fabrication, machine learning applications in electrodynamics, and investigation of electromagnetic properties of certain local flora and fauna.

Intelligent Systems Laboratory (ISL)

The goal of the laboratory is to advance research and teaching in smart, adaptive, and predictive system areas at Sonoma State. We define an intelligent system as: (i) Having equipped with sensors and necessary computing resources to read, analyze and interpret sensor input (smart), (ii) being able to use sensor data to adapt functions to achieve optimum outcomes (adaptive), and (iii) being able predict future outcomes (predictive). Specifically, the lab will advance research and training in sensors, embedded systems, and sensor data analysis areas. Located in Engineering Complex 2002, the lab has five workstations with computers, robotic arms, robotic car-kits, test and measurement equipment, embedded system boards, data acquisition boards, electrical tools and supplies, and a controlled sensor test set-up. A computer is built with graphic processing unit for machine learning-based projects. Currently, eight students working in five research projects regularly use the lab resources. Five students, including two high school students, worked from the lab in Summer 2018. One summer scholar was supported by the School of Science and Technology (SST) Dean’s Summer Research Award and two high school students were supported by the SSU High School Internship Program (SHIP). Robotics and Intro to Engineering courses use the robotic arms and cars for projects. One robotic arm was supported by the Dean’s office for teaching and outreach. All other acquisitions were made through the SST start-up funds.

Rolf Illsley Photonics Laboratory

Named after the founder of Optical Coating Laboratory, Inc. (OCLI), a major supporter of the MS-CES Program and a division of JDS Uniphase, this laboratory is equipped with the state-of-the-art photonics equipment. It is organized in six experimental stations each with equipment such as optical spectrum analyzers, optical power meters, sweep wavelength system receivers, microscopes, etc. Other major equipment in the lab are various types of light sources, splicing station, 48-ports AWG devices, a variety of couplers, connectors, etc. The students in photonics and optical fiber communications courses can characterize lightwave components and devices and optical fibers, and, study beam propagation behavior.
In addition, the laboratory is equipped with the optical and telecommunication software modeling tools from RSoft. This allows the students to simulate their experiments and compare the two results.

William Keck Microanalysis Laboratory

The Microanalysis Laboratory consists of four major instruments at the present time:

  • Hitachi Scanning Electron Microscope (SEM)
    The SEM instrument is configured to allow imaging of inorganic objects as well as the more difficult to prepare and analyze biological specimens. Magnification up to 300,000X is well within the range of the instrument. A sample holder allows us to maintain the sample temperature from -20C to +85C. In addition, to the traditional SEM functionality, this instrument is equipped with Energy Dispersive X-ray Analysis (EDX). We are able to collect full atomic elemental analysis on a per pixel basis of the entire SEM image. As such we obtain extremely magnified images while simultaneously measuring the elemental content of any portion of the image.
  • Olympus confocal imaging system
    The confocal imaging facility is equipped with an Olympus FV300 laser scanning system attached to an Olympus BX61 upright microscope. This system has three lasers: Argon (488 nm), Red HeNe (633 nm) and Green HeNe (543 nm) allowing the utilization of a wide range of fluorescent probes for specimen analysis. The unique feature of this instrument is its ability to generate 3D confocal images of a variety of living and non-living biological materials. With the help of an SIS Biological Suite Imaging Software, the digital camera attached to the above microscope system allows researchers to gather and analyze high quality bright-field, dark-field, phase and Nomarski-DIC images of specimens.
  • Pacific Nanotechnology Scanning Probe Microscope (SPM)
    The Pacific Nanotechnology SPM is a tool that allows us to measure the properties of atomic surfaces. Sometimes the SPM is referred to as an Atomic Force Microscope (AFM). The SPM or AFM is comprised of a very small and sharp tip, the point of which is only a few atoms in diameters. This tip is connected to a cantilever and is moved in a systematic way over the surface of the sample. The repulsive Van der Waals force between the tip and the sample results in the movement of the cantilever. That movement is imaged via a secondary laser system built into the instrument. Typical scan areas can vary from 100 nanometers(nm) X 100 nanometers up to 100 microns X 100 microns. A nanometer is 10-9 meters, while a micron is 10-6 meters. The height profile ranges from 0.1 nm to 100 nm. An instrument similar to this instrument recently certified the average roughness of the mirrors used in the new NASA x-ray telescope EXAFS.
  • PHI Auger spectrometer
    The PHI Auger spectrometer is an instrument that allows us to measure the strengths of various atomic bonds in a particular specimen. The EDX instrument mentioned above allows us to determine the presence of a particular atomic element in a specimen. The Auger spectrometer then allows us to probe the chemical nature of the specimen more deeply.

Each of the above instrument probes a different aspect of a particular sample. Therefore, combination of these instruments is actually more important than any one instrument. In combination, we can learn/deduce key mechanism in the formation of the sample. For example, we can determine whether a thin film was evaporated or sputter deposited. We can deduce the ability of a thin film sample to withstand abrasion and predict how well it will withstand harsh chemical environments.
