Most industrial microwaves operated in one of two unlicensed, government allocated radio bands called the Industrial, Scientific, and Medical (ISM) bands. The lower “L” band ranges from 902 to 928 MHz. In Europe and some other regions 896 MHz is used to avoid interference to the 900 MHz GSM cellular...

Microwaves are a kind of high frequency radio wave. In fact, the frequencies are the same as used by many consumer devices including cellular phones, WIFI, Bluetooth, and many other wireless devices. Radio waves (RF) are a type of electromagnetic waves called non-ionizing radiation. Despite uninformed slang about “nuking” a...

Microwaves produce a phenomenon called volumetric heating. Simply stated, they heat the entire mass of an object uniformly. This is because the microwave penetrated deeply into the object instead of just acting on the surface. Volumetric heating is unique to microwaves; almost all other forms of heating are conductive, where...

Microwave heating is a very versatile technology that can be used in a wide range of applications, so this question must be answered with respect to categories of applications.
Many industrial microwave systems are used to dry various organic and inorganic materials, or to defrost, cook, or pasteurize food products. This...

Very few drying technologies can approach microwave systems for positive environmental impact. In fact, in most cases environmental permitting is not required. Let’s consider the common types of possible emissions and examine how microwave system measure up.
Combustion Products such as NOx and COx: This is simple. There is no combustion...
