Calculating Z Axis Permittivity Anisotropy for Stripline Controlled Impedance Routing
Calculate stripline impedance by applying the geometric mean of in-plane and z-axis permittivity to sidewall fringing fields to eliminate 2-ohm routing offsets.
Quantifying Laminate Resin Anisotropy Dispersion and Phase Skew Limits in Gigabit Interconnects
Managing anisotropic permittivity and glass weave dispersion prevents timing jitter and intra-pair phase skew in gigabit differential interconnects.
Split Post Cavity Resonance Corrections for Anisotropic Substrate Core Permittivity
Split post cavity resonance measures in-plane substrate permittivity; z-axis core corrections prevent multi-ohm stripline impedance errors on woven glass panels.
Resolving Sub Millimeter Wave Dielectric Anisotropy and Interfacial Water Transport Kinetics in Quartz Reinforced Fluoropolymer Laminates
Sub-millimeter wave performance in quartz-fluoropolymer laminates depends on controlling anisotropic dielectric tensors and sealing interfacial moisture diffusion paths.
Understanding Directional Dielectric Permittivity Variance in Multilayer Stackups
Multilayer directional permittivity variance causes stripline capacitance shifts that must be corrected by modeling in-plane and out-of-plane dielectric constants separately.
Fundamentals of Directional Dielectric Permittivity in Multilayer Circuit Laminates
Directional dielectric permittivity variance in multilayer laminates requires evaluating in-plane and out-of-plane Dk tensors to prevent impedance errors.
