According to an embodiment, degree of depth subtended angle θ dwidth subtended angle θ can be less than w.In a particular embodiment, degree of depth subtended angle θ dabout 0 ° can be no more than, thus make the entry depth D of microwave emitter 822 0with outlet size D 1substantially identical, as shown in the embodiment in Fig. 9 d.In another embodiment, degree of depth subtended angle θ d0 ° can be less than, thus make D 1be less than D 0, as shown in figure 9e.When microwave emitter 822 comprises the degree of depth subtended angle being less than 0 ° and/or the degree of depth D launching opening 838 1be less than the degree of depth D of microwave entrance 836 0time, microwave emitter 822 can be the taper launch device with anti-section substantially.Comprising n at microwave emitter 822 launches in an embodiment of opening, and the opening between 1 and n can have the degree of depth of the entrance being less than or equal to reflector and/or the degree of depth of width and/or width.The further embodiment of many openings reflector will discuss in detail below.
According to one embodiment of present invention, the degree of depth D of opening 838 is launched 1can be no more than about 0.625 λ, be no more than about 0.5 λ, be no more than about 0.4 λ, be no more than about 0.35 λ or be no more than about 0.25 λ, wherein λ is the wavelength from the Main Patterns launching the microwave energy that opening 838 discharges.Although do not wish to be bound by theory, it is believed that by the degree of depth D by launching opening 838 1reduce to minimum, the microwave field that immediate transmitting opening 838 produces is more stable and even than the microwave field produced by the reflector with the larger degree of depth.Comprising n at microwave emitter 822 launches in an embodiment of opening, the degree of depth d of each transmitting opening nabout 0.625 λ can be no more than, be no more than about 0.5 λ, be no more than about 0.4 λ, be no more than about 0.35 λ or be no more than about 0.25 λ.When microwave emitter 822 has multiple opening, each opening can have with same transmitter one or more other launch the identical or different degree of depth of opening.
Referring now to Figure 10 a-c, another embodiment being suitable for the microwave emitter 922 of microwave heating system described herein is shown, this microwave emitter comprise single microwave entrance 936 and for from wherein discharge microwave energy two or more launch openings, these two or more launch opening be illustrated as launch or exhaust openings 938a-c.Microwave emitter 922 shown in Figure 10 a-c comprises first, second, and third isolated transmitting opening 938a-c, and described isolated opening is distanced from one another cross.Define three although described herein and launch opening, but be to be understood that, reflector 922 can comprise the transmitting opening of any suitable quantity, and described any suitable quantity comprises at least 2, at least 3, at least 4 and/or be no more than 10, be no more than 8 or be no more than 6.First, second and the 3rd spacing between to launch in opening 938a-c each can be at least about 0.05 λ/at least about 0.075 λ or at least about 0.10 λ and/or be no more than about 0.25 λ/be no more than about 0.15 λ or be no more than about 0.1 λ, and wherein λ is the wavelength of the Main Patterns of the microwave energy discharged from reflector 922.

When one or more path 937a-c is different from the length of one or more other paths, the size (L of path 937a-c 1, L 2and/or L 3) can be adjusted, thus make the phase velocity of the microwave energy propagated by described path at the longer microwave path (L such as, in Figure 10 c 1and L 3) internal ratio is by the shorter path (L such as, in Figure 10 c 2) with leg speed accumulation faster.Although do not wish to be bound by theory, suppose can perform this kind of adjustment to guarantee the evenly synchronous of each waveform portion, thus when microwave energy is discharged in room 520, produce uniform wave surface.When microwave emitter 922 comprises single barrier film, only produce two microwave paths (this embodiment not shown) and the same length of each path.Therefore, can not need or seldom need to control the phase velocity through the microwave energy of equal length path.
In identical or another embodiment, each opening launched in opening 938a-c can limited depth d 1-3, as Figure 10 b illustrates substantially.In one embodiment, degree of depth d 1to d 3in each degree of depth can be substantially identical, and in another embodiment, degree of depth d 1-d 3in at least one degree of depth can be different.As discussed previously, d 1-d 3in one or more degree of depth can be no more than about 0.625 λ, be no more than about 0.5 λ, be no more than about 0.4 λ, be no more than about 0.35 λ or be no more than about 0.25 λ, wherein λ is the wavelength of the Main Patterns from the microwave energy launching opening 938a-c discharge.In addition, in one embodiment, discuss in detail as previous, d 1-d 3in at least one can be less than or equal to the degree of depth d of entrance 936 0.As shown in fig. lob, when barrier film 940a, 940b exist, the degree of depth d of each transmitting opening 938a-c 1-3do not comprise the thickness of described barrier film 940a, 940b.
