DESCRIPTION:Abstract\n\nSkin cancer is the most common form of cancer in th
 e world. A report by the skin cancer foundation estimates that one in five
  Americans will develop skin cancer by the age of 70. Melanoma\, which is 
 considered to be the deadliest type of skin cancer\, causes the majority o
 f fatalities. The other type is non-melanoma\, which is further classified
  as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC)\, affects
  millions of human lives every year.\n\nEarly-stage diagnosis of all skin 
 cancers\, including melanoma\, results in a better prognosis and improved 
 survival rate for the patient. The current method of diagnosis relies on t
 he visual inspection and therefore\, implicitly\, on the skill and experie
 nce of the dermatologist. They inspect the color\, size\, shape\, irregula
 rities in borders\, bleeding in lesions\, or if lesion is raised or hard t
 o touch. In case of a suspicious lesion\, a biopsy is required\, so that t
 he sample can be tested in a cell pathology lab. These methods of visual i
 nspection are vulnerable to human error and vary in interpretation accordi
 ng to the dermatologist’s experience.\n\nAs a result\, a significant resea
 rch effort is underway to develop diagnostic tools for skin cancer. Due to
  the reported inherent difference in electrical properties between healthy
  and cancerous tissues\, microwave-based techniques hold promise for skin 
 cancer detection.\n\nTherefore\, the main focus of this research is system
 atic design and development of experimental tissue-mimicking phantoms whic
 h are extensively required to check the viability and performance of the d
 esigned tools in a controlled laboratory environment and prior to in vivo 
 trials. The thesis describes the mathematical modeling and construction of
  series of phantom models and comprehensive dielectric property characteri
 zation of skin and skin cancer tissue-mimicking phantoms by measuring thei
 r reflectance properties in the microwave region. In addition\, the work c
 ontributes with the estimation of the Cole-Cole function parameters for ex
 perimental values that gives the best fit with the computed results. Sensi
 ng depth of the probe is quantified by realizing realistic phantoms of dif
 ferent thicknesses. Lastly\, the dielectric probe was numerically simulate
 d to estimate the specific absorption rate (SAR) in order to confirm the c
 ompliance with the safety standards.\n
