  Due to the non-ionizing property, researchers have chosen to investigate
terahertz radiation (THz) Imaging instrumentation for Bio-Sensing applications.
The present work is to design and fabricate a near field lens that can focus
guided terahertz radiation to a microscopic region for the detection of
cancer-affected cells in Biological tissue. Operational characteristics such as
field of view, optical loss factor, and hydrophobicity must be included to
achieve an effective design of the lens.
