Microwave oven equation
WebMicrowave (MW) drying is a technique based on electromagnetic waves that generate heat directly inside the product ( Lenaerts et al., 2024 ). MW radiation is a part of the electromagnetic spectrum ranging from 300 MHz to 300 GHz. As MW produces heat inside the food product, it causes rapid internal heating. Webthe basic simplified equations governing the microwave heating of a foodstuff. In Section 3 we describe the fast numerical method used to solve this system. In Section 4 we …
