چکیده مقاله :
Conventional techniques for diagnosing skin cancer include shape, size and skin tumor color, bleeding, a disorder in the tumor, and so on. The goal of researchers in this field of study is to find simpler and safer methods for cancer tumor detection. The conical dielectric probe will be an effective instrument for analyzing mankind’s tissue illnesses like the initial stage of skin cancer. This illness will be incredibly treatable when the tumors are distinguished at the initial stages. The possibility of making a probe to detect the cancerous cells with the least destructive side effect in the early stages was evaluated. Our research examined the input applied frequency variations (35GHz, 45GHz, 65GHz, and 90GHz) according to the microwave-based detection method and compared the obtained results, which are required for a better understanding of heat transfer and necrotic properties in the biological objects. According to the microwave reflection characteristics, developed models and simulations based on the finite element method, by increasing the frequency, the temperature change increases, and the proportion of damaged tissue increases slightly after 10 minutes of millimeter wave exposure.
