Surface phenomena such as surface plasmon resonances play an important role in sensor technology since the behavior of electromagnetic fields at material interfaces can be directly correlated to many physical and chemical properties of the materials. These sensing methods have the further benefit of allowing for accurate and non-invasive sensing that can provide immediate results both in and out of a laboratory. Sensors based on surface plasmons are being increasingly incorporated directly into larger systems to detect many properties, including temperature and the presence or concentration of particular compounds in medical, industrial, or other fields.
The need to incorporate optical sensors into a wide variety of applications necessitates the creation of smaller sensors that are easy to fabricate with and used in existing semiconductor technology. However, as the size of any optical device, including sensors, decreases, the need for simulation software increases.
