Photonic Band Gap Structure for a Particle Accelerator

CST MICROWAVE STUDIO® has been successfully applied to the simulation of a photonic band gap structure for a particle accelerator. Due to the high-Q nature of the device, the Eigenmode Solver with Modal Analysis was chosen.

Figure 1: CST MWS Model of the device

Figure 1 shows the geometry of the device which was constructed using the intuitive and powerful user-interface of CST MICROWAVE STUDIO.

A series of metallic cylinders are arranged between two hexagonal plates creating the periodic meander for focusing of the field. Two coaxial probes are placed at the top and bottom of the structure as shown also in figure 2 to excite the desired mode.

Figure 2 shows a photo of the actual device as described above....



Figure 3: Eigenmode Field Patterns at 14.42 GHz

An Eigenmode Analysis has been performed to obtain the correct mode of excitation. The H-Field Vector and Contour Patterns at 14.42 GHz are shown in Figure 3.



Figure 4: Modal Analysis S-Parameters

Figure 4 shows the results from a Modal Analysis of the Eigenmode results compared to measurement. The simulated results are in excellent agreement with the measured results confirming that the Eigenmode Solver is perfectly suited to the simulation of extremely high-Q structures.
