Embodiment approach 1
[0093] figure 1 It is a diagram for explaining the principle of operation of the permittivity estimating device according to Embodiment 1 of the present invention. First, use figure 1 A method of discriminating dielectrics using microwaves will be described.
[0094] exist figure 1 , schematically depicts TE waves (transverse electric waves: transverse electric waves) and TM waves that irradiate polarized waves of electromagnetic waves to objects to be measured (5A / 5B) with the same dielectric constant (εn) and different thicknesses (X1 / X2). Wave (transverse magnetic wave: transverse magnetic wave) each reflected wave.
[0095] figure 1 (a) schematically shows the state of reflected waves when the object 5A having a dielectric constant of "εn" and a thickness of "X1" is irradiated with TE waves and TM waves of polarized waves of electromagnetic waves. figure 1 (b) shows the state of reflected waves when the object 5B having a dielectric constant of "εn" and a thickness of...
Embodiment approach 2
[0167] Image 6 It is a block diagram showing a schematic configuration of a microwave heating device according to Embodiment 2 of the present invention. exist Image 6 The shown microwave heating device is configured to include the permittivity estimating device of the first embodiment described above. In the description of Embodiment 2, elements having the same functions, structures, and operations as those described in Embodiment 1 are given the same reference numerals, and descriptions thereof are sometimes omitted in order to avoid redundant descriptions.
[0168] Image 6 The microwave heating device according to Embodiment 2 shown is a heating cooker represented by a microwave oven, and has a heating chamber 13 as a storage portion (measurement area MA) of the dielectric constant estimating device in the main body of the device.
